TL;DR: Privacy lawsuits in 2025 aren’t won by theories — they’re won by evidence. If you’re dealing with CIPA (California Invasion of Privacy Act) or GDPR, you need more than cookie banners and policies. You need forensic-grade logs, screenshots, and legal mapping that stand up in court. That’s what this guide is about: how to turn tracking activity → admissible courtroom reports. Why Evidence Matters (Not Just Policy Text) Privacy lawsuits are exploding: CIPA §638.51 in California → covers trap-and-trace style interception. GDPR Articles 5–7 in Europe → require lawful basis before data collection. 👉 The core issue: timing of consent. And screenshots alone? They won’t cut it. Courts want HAR logs, DNS captures, payload headers, and mapped statutes. What Counts as Admissible Evidence Think…  ( 7 min )

In everyday API development, mocking is almost unavoidable. Whether it’s fast iteration at the early stage of a project or when an endpoint isn’t ready yet, mocking ensures front-end development continues smoothly—even without real backend data. Imagine this scenario: Pay Now," your front-end calls the backend /pay endpoint, which should return something like: { "data": { "code": 0, "message": "success", "pay_dtime":"2025-08-10 10:00:00", "order_id":"sn12345678" } } But the problems are: The backend isn’t ready, so you can’t test the post-payment flow. The payment API depends on an external gateway, not configured in the test environment. Some endpoints require complex authentication or data prep, making them unusable early. Waiting on backend devel…  ( 7 min )

Contact centers serve customers from diverse linguistic backgrounds, creating unique communication challenges. They connect customers and agents across continents—but language isn’t the only hurdle. Even when both parties speak the same language, accents, dialects, and speech patterns can create communication friction. Miscommunication across parties caused by an unfamiliar accent can snowball into longer handling times, repeated clarifications, and frustrated customers. Over time, these small disconnects erode customer satisfaction and inflate operational costs. Accent conversion software for contact center has bridged these gaps. The technology uses advanced AI and speech processing to dynamically neutralize accents in real time. The platform preserves emotional tone and natural speech f…  ( 9 min )

If you’ve sat through a cloud keynote lately, you’ve heard the terms multi-cloud and hybrid cloud. They sound futuristic — but behind the buzz are two very different strategies. Multi-cloud is about choice and resilience: pick the best tool from AWS, Azure, GCP, or smaller providers, and never get stuck with one vendor’s bill. The tradeoff? More complexity, more dashboards, and higher skill requirements. Hybrid cloud is about governance: keeping sensitive data or legacy systems on private infrastructure while bursting elastic workloads into the public cloud. Great for banks, healthcare, and government. Less great for small startups that just need to ship. Both approaches are valid, but neither is magic. The smartest teams focus less on buzzwords and more on execution: portability, observability, and cost control. So — is your company leaning into multi-cloud flexibility, or keeping things hybrid for compliance?  ( 6 min )

⚔️ AOT Showdown: .NET vs Java in 2025; Who’s really production-ready? In the race to optimize startup time, memory footprint, and deployment simplicity, Ahead-of-Time (AOT) compilation has become a game-changer. Both .NET and Java have embraced AOT, but not equally. If you're building microservices, serverless apps, or containerized workloads, knowing which platform delivers a smoother AOT experience can save you hours of frustration. AOT compiles your code into native machine instructions before runtime, unlike Just-In-Time (JIT) compilation, which happens during execution. This means: Faster startup Lower memory usage No runtime dependency on the VM or runtime engine But the devil’s in the details. Microsoft introduced Native AOT as a first-class citizen in .NET 7 and refined it in .NET …  ( 7 min )

Durante minha trajetória profissional, muitas vezes me vi em busca de um objetivo utópico: escrever o código perfeito. Refatorava, revisava, reescrevia. Olhava para cada detalhe como se, em algum momento, existisse um estado ideal em que o código finalmente fosse intocável. Adivinha? Esse momento nunca chegou. E não é porque eu falhei. É porque o código perfeito NÃO existe. O que existe é o melhor código possível dentro do contexto atual: considerando as prioridades da companhia, as pressões de negócio, o tempo de entrega e até a maturidade do time. A obsessão pelo “código perfeito” é perigosa porque ignora uma realidade simples: nós, desenvolvedores, somos protetores do código, sim, mas também somos entregadores — e somos pagos para entregar valor.

Until recently, quality live streaming from embedded devices like an ESP32 was severely limited. ESP32-CAM boards can only produce low-quality, low frame rate (5-15 FPS) streams of MJPEG images via RTSP at resolutions like 320x240. These microcontrollers simply didn't have enough CPU and RAM for real video processing with modern codecs. Then Espressif changed everything by releasing the ESP32-P4-Function-EV-Board, which features a dual-core 400MHz RISC-V processor, 32MB PSRAM, and most importantly, a hardware H.264 encoder capable of 1080P@30fps streaming. It's a game changer to be sure, but all of that hardware is nothing without a software library to push those beautifully encoded H264 streams to a valid destination. Thankfully Espressif came through again with the esp-webrtc-solution li…  ( 8 min )

Bringing a new drug to market is a long and complicated journey. From lab research to clinical trials, one of the biggest hurdles is compliance—the endless paperwork and documentation required by regulators. For years, this process has been slow, manual, and prone to errors. Now, a new kind of technology—Agentic AI—is changing the game. Instead of being just another tool, it acts like an autonomous assistant that can manage the entire process of preparing regulatory submissions. Why Compliance Has Been So Hard Traditionally, regulatory teams spend months compiling and reviewing thousands of pages of data.

When learning backend development, one of the best ways to practice is by building something practical and relatable. For me, that turned out to be a Bank App API — a Spring Boot project where users can create accounts, deposit and withdraw money, check balances, and even close accounts. This project gave me hands-on experience with Spring Boot, Spring Data JPA, and REST API design, while also teaching me how to think about real-world requirements like account numbers and user authentication. Spring Boot – for building the REST API. Spring Data JPA – for interacting with the database. Maven – build and dependency management.

🔹 What is Sharding in Databases? Sharding is a database partitioning technique where data is split across multiple databases or servers (called shards) to improve scalability and performance. Each shard contains a portion of the data (not a full copy). For example: Suppose you have a users table with 100 million rows. Instead of storing all in one DB, you could split: Shard 1 → users with IDs 1–25M Shard 2 → users with IDs 25M–50M Shard 3 → users with IDs 50M–75M Shard 4 → users with IDs 75M–100M Now each shard only handles a subset, so queries and writes become faster. 👉 Sharding is commonly used in very large-scale systems (e.g., Facebook, Twitter, YouTube) where one DB server cannot handle all the load. Sharding is just one of many scaling/distribution techniques. Let’s compare: Rep…  ( 8 min )

In our everyday lives, we rarely make important decisions based on just one opinion or perspective. For example, before buying a car, we usually seek out multiple reviews, consult with friends, and do our own research before finalizing the decision. Similarly, before watching a movie, most of us ask friends for reviews—unless it features our favorite actor or actress. The reason is simple: one person’s view can be biased, but when we gather multiple perspectives, the collective wisdom often leads us to a more balanced conclusion. This process of combining different perspectives to eliminate bias is not limited to human decision-making—it is also a core principle in the field of machine learning and data science. In analytics, this is known as ensembling. Ensembling combines multiple models…  ( 10 min )

Handling time zones and offsets is crucial for developing robust applications that operate across different geographical regions. Java's modern Date and Time API, introduced in Java 8, provides a comprehensive and immutable set of classes for this purpose. A time zone is a region of the globe that observes a uniform standard time for legal, commercial, and social purposes. It's essentially a set of rules for converting local time to a universal time, and it's important because it accounts for daylight saving time (DST) and other regional variations. Using time zones correctly is vital for: Accuracy: Ensuring that timestamps are correct, regardless of where the user is located. For example, a meeting scheduled for "2 PM" in New York must be converted correctly for someone in London. Data In…  ( 8 min )

JavaScript Code Blocks: The Ultimate Guide to Mastering the Mighty { } You see them everywhere. They are the unsung heroes, the silent guardians of structure and logic in the world of JavaScript. They are the humble curly braces: { and }. Together, they form a JavaScript Code Block. If you've ever written a function, an if statement, or a for loop, you've used a code block. But have you ever stopped to think about what they really do? How they control the visibility of your variables? How they are the very foundation of writing clean, maintainable, and powerful code? Many beginners treat them as mere syntax, a necessary ritual to make the code run. But understanding code blocks is a fundamental leap from writing code that works to writing code that is elegant and professional. In this co…  ( 12 min )

Introduction Accurate forecasting isn’t about chasing the fanciest algorithm — it’s about getting the basics right first. This post argues that clean, well-structured data plus the right mix of models, tools, and human judgment produce far better forecasts than complexity for its own sake. The payoff: fewer stockouts, less tied-up cash, and smarter decisions across the business. Garbage in, garbage out: flawed inputs guarantee poor forecasts. Clean, enrich, and standardize historical data before modeling. Hunt down outliers (one-off bulk orders, typos, misplaced decimals), correct or remove them to avoid skewed predictions. Don’t lump everything together — segment by product line, geography, customer type, etc. Build multiple micro-forecasts (e.g., sparkling water in Arizona vs. hot c…  ( 7 min )

Why we need init? 1. Purpose of init.py init.py file in a directory tells Python that the directory should be treated as a package. This allows you to import modules from that directory using package syntax, e.g.: Without init.py, Python (pre-3.3) would not recognize the folder as a package, and imports might fail. The file can be empty, or it can contain initialization code for the package. Starting with Python 3.3 and above (including Python 3.11), you can technically remove the init.py file from a package directory, and Python will still recognize it as a package due to "implicit namespace packages." init.py: When you add an init.py file to a package directory, it does not create a global namespace. Instead, it defines a package namespace. All modules and submodules…  ( 8 min )

These days, we all stream everything: movies, shows, random videos we find online. But the big streaming platforms often come with strict rules, changing algorithms, and sometimes even censorship. For small creators, that can be exhausting. So many creators are taking a different path: building their own little streaming spaces. Smaller, more personal platforms where they can share what they want, connect directly with their audience, and stay in control over their content. Building your own platform can be tough, especially when it comes to setting up the backend and database. In this guide, we’ll explain step-by-step so even beginners can follow along and create a working video-on-demand platform in a single afternoon.

操作系统的多线程 进程是操作系统分配资源的最小单位，每创建一个新的进程，会把父进程的资源复制一份到子进程。而线程是一种轻量级的进程，不独立拥有系统资源，操作系统内核是按照线程作为调度单位来调度资源。每一个进程是由一个或者多个线程组成的。 进程中 Text、Data、BSS 和 Heap 部分线程之间共享，Stack 不共享，每个线程拥有自己独立的栈。 Linux 系统中普遍使用 pthread 库开发多线程程序，pthread 符合 POSIX 标准，提供管理和操作线程的方法，包含在 pthread.h 头文件中。同一个进程中，除了栈，所有线程共享同一份内存，同时因为线程的执行是并行的，所以不可避免地发生资源竞争的问题，即同一时间有多个线程试图获取或者修改同一个内存资源。当开发者小心翼翼地处理内存使用时，并行地读写内存可以带来效率提升，一旦不注意可能带来严重的问题。假设用 2 个线程执行如下代码，counter 的结果可能远小于 2000 ： for (int i = 0; i < 1000; i++) counter++; pthread 提供了锁来解决这个问题，最常见的锁是互斥锁和读写锁。 互斥锁：同一时间只能有唯一一个线程访问，使用 pthread_mutex_t 读写锁：同一时间只能有唯一一个线程写入，允许多个线程读取， 使用 pthread_rwlock_t 这里不打算展开 Linux 多线程编程，超出了本篇讨论的重点。 浏览器是一个多线程应用，我们在《web 应用榨干 CPU 性能的正确姿势》一文中介绍过这些线程，这里引用一张图： 这些线程由浏览器管理，开发者并不能干预，可以把这些线程看作是“不可编程”的多线程；浏览器像开发者提供了“可编程”的多线程，那就是 Worker 。《web 应用榨干 CPU 性能的正确姿势》介绍了在 JavaScr…  ( 7 min )

For decades, passwords have been the primary key to digital security. Whether it was logging into an email account in the early 2000s or accessing sensitive financial data today, the first line of defense has almost always been a password. But as cyber threats become more sophisticated and user behavior more careless, the traditional password is starting to look less like a security solution and more like a liability. Let’s break this down. Why Passwords Became a Problem Phishing: Cleverly crafted emails or websites trick users into entering their passwords. Password fatigue: Users struggle to remember dozens of unique passwords, leading to poor practices like writing them down or using “123456.” This password chaos gave rise to password managers, tools that store and autofill complex pass…  ( 9 min )

Most modern startups gravitate toward cloud platforms (AWS, GCP, Azure) or specialized hosting services like DigitalOcean, Linode, or Vercel. Look for: Pay‑as‑you‑go pricing – you only pay for the resources you actually consume. Predictable cost alerts – set budget thresholds to avoid surprise bills. Built‑in scaling – auto‑scaling groups or serverless functions that grow with traffic. P…  ( 8 min )

A website is more than just content. The way it looks and reacts to user actions creates the real experience. In JavaScript, the Document Object Model (DOM) acts as the bridge between your HTML structure and the scripts that can change it. By learning how to manipulate styles and classes, you can make a page come alive; whether that’s switching between light and dark mode, highlighting active links, or animating elements on click. This guide is designed for beginners who want a clear and practical introduction to changing styles and classes with JavaScript. By the end, you’ll understand: How to select HTML elements before applying changes. How to use classList to add, remove, toggle, and replace classes. How to apply inline styles directly with JavaScript. How to update CSS variables (cust…  ( 8 min )

Imagine this: you’re building an app where users expect instant updates—chat messages delivered in milliseconds, dashboards updating without refresh, or collaborative tools that feel alive. At that moment, the database you choose is not just storage; it’s the heart of your product. But here’s the catch—do you go with Firebase, Supabase, or Postgres with real-time extensions? Each promises speed, scalability, and developer happiness, but only one might be the right fit for your project. Let’s break it down. Google’s Firebase is often the first name that pops up when developers think “real-time.” Strengths: Blazing fast data sync across devices. Massive ecosystem: Authentication, Hosting, Analytics, Push Notifications. Great for quick MVPs and startups. Things to Watch: Vendor lock-in (you…  ( 7 min )

The Struggle of Learning GCP I’ll be real with you. The first time I had to spin up resources on Google Cloud Platform (GCP), I felt like someone had just dropped me in the cockpit of a spaceship. I knew AWS pretty well, but GCP? That was a different beast. Compute Engine, BigQuery, IAM policies… the concepts weren’t foreign, but the implementation details sure were. I wasted a ton of time bouncing between YouTube tutorials, stale blog posts, and official docs before I found platforms that actually worked. So, if you’re wondering, “What’s the best platform to learn Google Cloud Platform?” I’ve been exactly where you are. Here’s my no-nonsense breakdown of the platforms I’ve tried (and what I’d actually recommend if you don’t want to waste weeks). If you don’t want to read the whole list, h…  ( 8 min )

Choosing a translation API is harder than it looks. Prices vary by character and by feature. Quality depends on language pair, domain, and how well you enforce terminology. Rate limits and quotas can break production if you learn about them too late. This guide gives dev teams a practical way to compare options, plan for limits, and avoid lock-in. Most teams start with a demo that translates a few sentences, then extrapolate to production. That skips the messy parts that fail at scale. Think about these before you write the first line of glue code: Volume shape: steady trickle, periodic spikes, or nightly batch. Content type: plain text, HTML, subtitles, office docs, or PDFs. Terminology control: product names, legal terms, or industry abbreviations. Compliance: data residency, retention, …  ( 11 min )

Donkey Kong Bananza’s DK Island is all about nostalgia, packing in callbacks to Rare’s glory days but offering little new beyond a warm, fuzzy tour of old haunts. It really feels like it should’ve been a free post-game treat instead of paid DLC. Emerald Rush, on the other hand, is where things get spicy. You’ll bounce through familiar levels with crazy parkour tricks, mix and match perks for wild new strategies, and chase high scores in a roguelite spin on Kong’s world. It clocks in around 10 hours, and while more enemies or abilities would’ve been nice, it’s a solid pick if you crave extra DK action—just don’t expect it to reinvent the wheel.

In the Modern Data-Driven Landscape In the modern data-driven landscape, we're drowning in information but starved for wisdom. Traditional Business Intelligence (BI) dashboards, once the pinnacle of data accessibility, are becoming rigid bottlenecks. They are slow to build, difficult to adapt, and often require a specialized analyst to decipher. What if you could just ask for the data you need and get a perfect visualization in seconds? This isn't science fiction. We built it. This is the deep-dive story of how we engineered a conversational AI reporting agent that transforms natural language questions into insightful, actionable data visualizations. For years, the process has been the same: a business user has a question. They file a ticket. An analyst interprets the request, wrangles t…  ( 12 min )

What Is Functional Programming? A pure function is a function whose output value follows solely from its input values without any observable side effects. In functional programming, a program consists primarily of the evaluation of pure functions. Computation proceeds by nested or composed function calls without changes to state or mutable data. In Python, functions are first-class citizens. This means that functions have the same characteristics as values like strings and numbers. Anything you would expect to be able to do with a string or number, you can also do with a function. >>> def func(): ... print("I am function func()!") ... >>> func() I am function func()! >>> another_name = func >>> another_name() I am function func()! **>>> def func(): ... print("I am funct…  ( 7 min )

In Part 1, we covered TypeScript and Angular Core Concepts (Q1–Q50).

Difference between switchMap, mergeMap, concatMap, and exhaustMap? switchMap → cancels previous observable, subscribes to latest. mergeMap → runs all observables concurrently. concatMap → executes one after another in order. exhaustMap → ignores new until current completes. Q52. What is the difference between forkJoin and combineLatest? forkJoin → waits for all observables to complete, emits once. combineLatest → emits whenever any observable emits (after all have emitted at least once).…  ( 9 min )

I used to code like I was playing Tetris. Drop a function here, squeeze a feature there, hope everything fits together without breaking. My GitHub was full of projects that worked but couldn't explain why. My code reviews were defensive battles where I'd rationalize decisions I'd made on autopilot. Then I spent 90 days forcing myself to think before I typed, and everything changed. Not the usual "learn a new framework in 30 days" challenge. Not another productivity hack promising 10x developer status. This was different: a deliberate practice routine that rewired how I approached problems at the system level. The transformation wasn't about writing better code. It was about developing the mental models that make code inevitable—the kind of architectural thinking that separates developers w…  ( 11 min )

Data races in C++ multithreaded applications occur when multiple threads try to access a single data without proper data locking tools like mutex. Concurrent Reads and Writes : If one thread reads a variable while another writes to it without synchronization, a data race occurs. Concurrent Writes : If multiple threads write to the same variable concurrently without synchronization, it leads to a data race. Lack of Synchronization Primitives : Not using mutexes, atomic operations, or other synchronization mechanisms can result in data races. Data race may cause unpredictable output and even crashes. For example, look at the below C++ programs. Here two threads are trying to access a single variable without a proper synchronization technique. Here is the video in which the program is run i…  ( 7 min )

Introduction If you’ve been working with Laravel 12, you already know that the event–listener mechanism is one of the most powerful features of the framework. Events allow you to decouple your application logic, while listeners react to these events with specific actions. But what happens when an event has multiple listeners and their execution order actually matters? For example, imagine an event UserRegistered with five listeners: one sends a welcome email, another creates a profile record, another logs analytics data, etc. If these listeners run in a random sequence, your business rules might break. In this article, we’ll explore a scalable, enterprise-grade solution that lets you explicitly define the execution order of event listeners in Laravel 12 while keeping the lookup compl…  ( 8 min )

Are you using Springboot and Kotlin? Have you heard about spring AOP? If not then some of spring annotations like @HandlerInterceptor, @Transactional may not work as you except. Spring AOP primarily relies on creating proxies around your beans. When you apply an aspect to a method, Spring creates a proxy that intercepts calls to that method and applies the advice (e.g., @Around, @Before, @After). This mechanism generally works for suspending functions as well. But when using AOP based annotations. We must exercise caution and test them. Proxies are for cross-cutting concerns: Web Request Handling - HTTP request/response processing, validating request, serialising and deserialising request and response, processing headers, so on ...

Companies are relying more on Content Management Systems (CMS) to manage growing content needs. But when a CMS becomes more of a burden than a benefit, it’s time for a change. Our global video game publisher client had built their CMS on Nuxeo, but the platform proved costly, complex, and underutilized, all while raising concerns about vendor lock-in and data ownership. They needed a lighter, more flexible, and scalable solution. We turned to Strapi, a headless, flexible CMS that met those goals. While Nuxeo provides extensive capabilities, our client faced challenges, including: Vendor Lock-In: Proprietary data structures limited portability, while rigid workflows and constrained schema customization restricted flexibility. This created long-term dependency on Nuxeo and slowed the team’…  ( 10 min )

TL;DR: I was calling my Rust SMS proxy on a Google Cloud VM by IP:8080, which caused Cloudflare 1003 errors and browser warnings. I mapped a hostname (example-proxy.example.com) to the VM, opened ports 80/443, put Caddy in front of my Rust app, and let it auto-issue a Let’s Encrypt certificate. Result: clean HTTPS endpoint that “just works,” and an easy env var for my Cloudflare Worker: SMS_API_URL=https://example-proxy.example.com/sms/send. I built a Rust program that proxies SMS requests. It ran fine at http://203.0.113.45:8080, but when I integrated it with a Cloudflare Worker and the frontend, I started seeing: 404 Not Found (from my origin on routes I hadn’t defined yet) Cloudflare 1003 (when requests were made by IP instead of a hostname) This post documents what the errors actually …  ( 10 min )

Introduction   Every user has the same goal — to use your product effectively and efficiently. Only then will they decide it’s a good fit for their needs. And if a user can’t find value in your product, it won’t take long for them to move on to something else.  Usability testing is an essential part of testing a new product. It allows us to find problems, fix issues, and create a better product. However, even if you know that usability tests are essential, choosing between different tests can be challenging. If your product is not user-friendly, you’ll lose customers, which can damage your company’s reputation.  In this article, we’ll share the best four usability testing methods. Usability testing, also known as a user experience test or UX test, is a method of evaluating the effectiven…  ( 12 min )

I was pair programming with my senior engineer Sarah last week when she asked Claude to help refactor our payment processing logic. The AI suggested elegant code patterns, perfect syntax, beautiful abstractions—and completely broke our fraud detection system. "The problem isn't the code," Sarah said, staring at the failing tests. "It's that Claude doesn't know our system. It's writing poetry when we need architecture." This moment crystallized something I've been wrestling with across my two decades building scalable platforms: AI assistants have become incredibly sophisticated syntax helpers, but they're flying blind when it comes to understanding our actual systems. They can write perfect React components without knowing your design system, craft beautiful API endpoints without understan…  ( 12 min )

If you’re a Ruby on Rails developer, chances are you’re here because you care about writing cleaner, smarter code. Rails gives us a great starting point, but as apps grow, things can get messy fast — fat models, overstuffed controllers, and callbacks that feel like ticking time bombs. That’s where design patterns step in. They’re not about adding complexity — they’re about giving your code structure, flexibility, and clarity. The best part? You don’t need to learn all 20+ patterns. In real-world Rails projects, developers usually rely on just a handful. In this post, we’ll explore 5 design patterns you’ll actually use in Rails — patterns that help refactor fat models, simplify controllers, and keep your app clean. 1.

Production-grade navigation in React Router isn’t just useNavigate('/path') sprinkled everywhere. Centralize it. Type it. Test it. This post shows a reusable navigation hook (useRouteNav) and how to wire it into components like a pro. A tiny custom hook that wraps useNavigate and useLocation with typed, reusable intent methods. A Topbar component with a Create Customer button that navigates to /addCustomer. A HomePage that wires search + navigate together. Optional: List cards that navigate to /customers/:id on click. A tidy router using createBrowserRouter (with Suspense for lazy pages). A minimal CustomerAddPage stub to complete the flow. This pattern scales nicely: all app navigation lives in one place.

so i was bored one night and made this little tree simulation thing. took like an hour, thought it was cool, then forgot about it for months in my trash folder. later i was working on pathforge (interactive fiction tool) and spent days trying to figure out tree layouts for story nodes. nothing was working. then i remembered that old file... here's the core part: class Branch: def __init__(self, start, angle, length, depth): self.start = start self.angle = angle self.length = 0 self.target_length = length self.depth = depth self.finished = False self.children = [] self.static = False def grow(self): if self.length = MIN_BRANCH_LENGTH: child = Branch(end, self.angle + delta, new_length, self.depth + 1) self.children.append(child) basically each branch grows and spawns kids when it's done. random angles make it look natural. ended up using this for pathforge's tree layout and it works pretty well. full code on github  ( 6 min )

I’ve been meaning to write this blog for a long time. This year, I went to Toronto Tech Week — and honestly, I had a fantastic experience. I met incredible people, had deep conversations, and built some great connections. But… you can’t go to a big tech event without running into at least a few Tech Bros. I don’t mean that as an insult.

A certain company plans to provide affordable housing benefits to married employees within the company. This benefit is only available to families where both spouses are within the company, and one of the conditions is that the age of the couple is 70 years old or above. Here is the employee information table of the company: Employees： Try to identify families with total age of 70 and above. To solve this problem, simply replace the employee fields in the relationship table with the corresponding employee records, and then directly extract the corresponding employee's date of birth. Next, calculating age, age sum, and filtering operations will be very easy. Try.DEMO A3 uses the switch function to replace the employee ID in the relationship table with the corresponding employee record. This way, the employee's date of birth can be obtained to calculate their age.

Ever wondered how deployment practices evolve as you move from student projects → startups → big tech? This video breaks it down in the most entertaining way possible. Here’s the technical summary: Uploads files directly to production. No CI/CD, no rollback strategy. Tools: scp, FTP, or manual uploads. Risk: High. Environments: Local → Test → Production. Backend: Node.js + Express.js. Hosting: AWS EC2. Workflow: Code pushed → tested manually → deployed manually. Better than student level, but still fragile. CI/CD pipelines (GitHub Actions). Every commit triggers automated build + integration tests. Auto-deploy to test, then to production if tests pass. Rollback if deployment fails. Consistent, scalable, reliable. CI/CD for automation. Environment separation (local, test, prod). Testing & rollback for reliability. AWS EC2 + Node.js/Express.js for hosting & backend. 🎯 Final Thoughts The video is not only hilarious but also a practical teaching tool: Students see why manual deployments don’t scale. Startups learn why staging environments matter. Developers get a glimpse of how big tech handles deployments at scale. 👉 As your project grows, automation and testing are no longer optional. They’re essential.  ( 6 min )

This is a simplified guide to an AI model called Roop maintained by Okaris. If you like these kinds of analysis, you should join AImodels.fyi or follow us on Twitter. The roop model, also known as chameleonn, provides one-click face swapping capabilities for both images and videos. Created by okaris, this tool enables users to seamlessly replace faces in media content with minimal effort. Unlike advanced-face-swap which focuses on swapping one or two people into target images, or become-image which adapts faces into different image styles, this model emphasizes simplicity and speed for straightforward face replacement tasks. The model shares similar functionality with roop_face_swap, offering comparable video face swapping capabilities. The model accepts source and target media files along with several control parameters to customize the face swapping process. Users can maintain video frame rates and enhance facial details through optional settings. source: The image or video file containing the face you want to use as replacement target: The image or video file where you want to apply the face swap keep_fps: Boolean option to preserve the original frame rate of video content keep_frames: Boolean setting to maintain all frames during video processing enhance_face: Optional enhancement to improve facial detail quality in the output Output array: Collection of processed media files with completed face swaps applied This face swapping technology processe...

The 2 a.m. Debugging Special It’s 2:07 a.m. 120 items in stock. 0. 42. The database insists there are plenty. The cache says sold out. The frontend store is oscillating like a ceiling fan with a bent blade. The local offline cache is basically a time capsule from last Thursday. And feature flags? They’ve split the timeline into alternate universes where customers either can’t buy at all - or get the last unit forever. I’m not debugging software. I’m cross-examining witnesses. Each one says, “I’m the truth.” None of them are. On the whiteboard, it was a thing of beauty. Database at the core. A cache to keep it lean. An in-memory store for hot paths. A frontend store to normalize state. A local copy for offline kindness. Feature flags for safety. Analytics humming quietly in the background…  ( 7 min )

If you work in tech, risk, or leadership, you know how much work goes into passing audits. Teams push hard to meet the rules of standards like SOC 2, ISO 27001, HIPAA, or PCI DSS. Everyone feels great when they get that certificate. The sales team can now show the world: "We are compliant!" This is a real achievement. It shows you are serious, builds trust with customers, and is often a must-have to win business. But this leads to a dangerous and tempting false idea: the belief that if you are compliant, you are secure. You are not. Mixing up these two ideas is a serious and costly mistake. Compliance is a picture of your security at one moment in time, based on a fixed set of rules. Security is the ongoing, always-changing fight to protect your systems from clever and adaptive attackers.…  ( 9 min )

Introduced as stable in Next.js 13.4, the App Router represents a major leap forward compared to the traditional Pages Router.

Once upon a Unix timestamp, WebKit added a set of CSS attributes, and viewport-fit meta tag, to help developers adjust their web apps for the iPhone X. Although these attributes still work for the iPhone, I am surprised that these features does not work in iPadOS 26, which of course, featured more rounded corners, and a new windowed mode with the "traffic light" window controls overlaying each running app. This image below shows the exact same demo running on iPadOS 26.0 (23A341). When I thought Apple would use the same env() variables to re-adjust the layout of web apps to be more immersive in windowed mode, This is what I got with: The window controls covering the "Blog" link. Imagine if another app has a hamburger menu icon blocked by the same controls A black gap between the viewport content and the top window edge. It could have been better to allow env(safe-area-inset-top) to offset the site content from the window decoration/controls, while maintaining the immersive look and feel for the new iPadOS (and possibly macOS, too). Unless when the web app developers want to replicate the common Mac look and feel, with window controls properly aligned with the website's navigation bar. I am in full support of this too, considering the immersive benefits for both GNOME and Windows.  ( 6 min )

For a long time, software development and security were separate. Development teams focused on building features quickly. Security teams focused on finding risks and vulnerabilities. They worked in silos. Developers would finish an application and then "throw it over the wall" to the security team for testing right before launch. This caused last-minute panic to fix issues, delayed releases, and frustrated everyone. This old way of working is no longer just inefficient; it's unsafe. Today, cyberattacks are common, and one software weakness can lead to a major data breach. Security can't be an afterthought. It must be built into every step of the development process. This is the main idea behind DevSecOps—and it is now essential for any company that creates software. "Shifting left" means…  ( 8 min )

Hey there! Thanks for stopping by. I'm Mitch, a video game narrative designer. I’ll be honest: for a long time, I didn’t feel like a “real” narrative designer. I wasn’t at a big studio. I hadn’t shipped anything people had heard of. Most of my story experiments lived in half-finished docs, or just in my head. Everywhere I looked, other people seemed more official. More polished. More qualified. Maybe you’ve felt that too. Maybe you’ve thought: “I’m just a hobbyist.” “I’m just an indie dev.” “I just have a story idea — that doesn’t count.” But here’s the thing I’ve learned (and I have to keep reminding myself of): Being a narrative designer isn’t something you wait for someone else to grant you. It’s something you decide to be. We live in a world that celebrates public wins — launches, …  ( 7 min )

AI coding tools are reshaping how we build software. They speed up everyday tasks, reduce bugs, and help teams ship features faster. Recent government research, including GDS’s practical guidance on why you should use AI coding assistants in the public sector, matches what I’ve seen on real projects: pick the right assistant and you’ll ship more, with fewer oops-moments. Many developers also rely on versatile helpers like ChatGPT for debugging, code explanations, and quick prototypes. If you want an AI pair programmer built into your editor, try GitHub Copilot for real-time suggestions and completions.

Part 4 of the "From Zero to AI Agent: My Journey into Java-based Intelligent Applications" series Now that we have our MCPService handling tool connections, we need to add the "intelligence" to our agent.

Today we'll build a HTTP client that can talk to popular LLM providers like Groq and Google Gemini. No complex libraries, just modern Java HTTP calls with clean JSON parsing using records and Jackson. These providers are chosen for their generous free tiers, offering high token quotas ideal for prototyping and learning. Groq: Fast inference with Llama models, great for real-time apps. Its free tier supports up to 131,072 tokens per minute, allowing millions daily…  ( 9 min )

If you're not sure how to take advantage of Graphite but your colleagues are raving about it, here's what I wish I was told from the beginning when we started experimenting with Graphite at Semgrep. I propose a workflow that makes it easy to revise previous commits, reduces conflicts, and avoids having unrelated changes in the same PR. A stack of pull requests isn't really a stack of pull requests, it should be treated as a stack of changes. Even though technically each change in the stack ends up being a GitHub pull request as we know it, a stack of changes functionally is the equivalent of one large traditional GitHub pull request implementing a new feature in multiple steps. Here's how to think of a stack: A Graphite stack should be thought of as a sequence of changes necessary to deliv…  ( 10 min )

There was a time when education was like farming in its earliest form — slow, manual, and bound to the limits of muscle and daylight. The teacher’s chalk was the farmer’s plough, cutting furrows of knowledge into the soft soil of young minds. Lessons came in steady rows, planted with patience, harvested only after long seasons of repetition. It worked — but just like early agriculture, it was hard work with uneven results. Not every seed grew. The wind of forgetfulness carried some away; others struggled in the shadow of outdated methods. Today, however, we stand in an educational landscape that feels less like a humble field and more like a precision-engineered farm. In agriculture, mechanisation meant tractors, seed drills, and AI-driven soil analytics—machines that could plant, water, a…  ( 8 min )

In .NET development, Entity Framework (EF) Core is undoubtedly the king of the data access layer. It’s powerful, well-supported, and Microsoft’s official ORM (Object Relational Mapping) framework. But the best doesn’t always mean the most suitable. In certain scenarios, other ORM frameworks may outperform EF Core in terms of extreme performance, flexibility, or specific features. So, besides EF, which other ORMs in .NET are worth checking out? Let’s dive in. Before exploring ORMs, a stable and efficient .NET development environment is essential. For Mac users, this can sometimes be tricky due to environment and architecture differences. That’s where ServBay comes in.

JetBrains' flagship framework for mobile platforms, Kotlin Multiplatform, has come a long way, evolving to offer the promise of "write once, run everywhere." The framework allows you to share business logic across platforms, which required native UI implementations for each platform. With the advent of Compose Multiplatform, JetBrains has taken this concept even further, enabling a true "write once, run everywhere" experience. Built on top of Kotlin Multiplatform, Compose Multiplatform allows developers to share both UI and business logic across all supported platforms, including Android, iOS, Web (via Wasm), and Desktop (via JVM). While this is a major leap forward, it’s important to acknowledge that Compose Multiplatform doesn't fully solve the challenge of a one-codebase approach for a…  ( 7 min )

Many IT organizations struggle with a fundamental disconnect in their ITSM service delivery: they achieve technical metrics while failing to meet actual user needs. While service desks often celebrate meeting resolution time targets, end users remain frustrated with the quality of support they receive. This misalignment typically occurs because organizations focus on easily measurable metrics rather than meaningful outcomes that drive business value. To bridge this gap, IT teams must shift their approach from rigid process compliance to creating genuine service experiences that address users' business challenges. This transformation requires rethinking how services are designed, delivered, and measured to ensure they truly serve the people who depend on them. Modern IT departments must fu…  ( 9 min )

Why some locks are certified by master locksmiths, and others are bought at a hardware store. In a world where "military-grade encryption" is a common marketing term, how can you be truly sure that the technology protecting your most sensitive data is as secure as it claims to be? For governments, financial institutions, and healthcare organizations, this isn't a theoretical question—it's a regulatory requirement. The answer isn't found in a company's whitepaper, but in an independent, rigorous certification process. For cryptography in the U.S. and Canada, that answer is FIPS validation. It’s the difference between a product that claims it’s secure and one that has proven it under the scrutiny of a national laboratory.

In-app chat is precisely one of those features that becomes essential the moment your users expect it. You've seen it everywhere: the little chat bubble in your banking app, the messaging thread in your marketplace, the team channel in your project management tool. It's how users talk to support without leaving your app, how buyers and sellers negotiate deals, and how communities form around your product. But here's what's interesting: while chat feels simple to users (just type and send, right?), the decision to add it touches nearly every part of your product. It affects your engagement metrics, your support costs, your technical architecture, and potentially your entire user retention strategy. Yet despite these clear benefits, many product teams still hesitate. They worry about the imp…  ( 20 min )

If there’s one thing everyone working in tech has noticed, it’s that learning never stops. There’s always a new framework, a trending language, or even a different approach to solving old problems. That’s great, but it can also be exhausting. And many people end up asking themselves: how do I keep growing without getting lost in this sea of information? One answer I’ve found — and that I see other devs discovering too — is simple: share knowledge. Writing articles and participating in developer communities not only helps others but also keeps you motivated and engaged in your own learning journey. Have you ever thought you understood a concept, but when you tried to explain it to someone, realized you didn’t fully master it? That’s where writing articles makes a difference. When you put wh…  ( 8 min )

When building modern UIs, developers often face a choice: write custom CSS or use a framework. Tailwind CSS takes a different approach — it’s a utility-first CSS framework that gives you small, reusable classes to style your components directly in your HTML/JSX. 🚀 🔹 What Does “Utility-First” Mean? In traditional CSS frameworks (like Bootstrap), you get pre-designed components. Tailwind instead provides low-level utility classes that you can combine to build custom designs. For example, instead of writing this: /* custom CSS */ And then using it like: Click Me With Tailwind, you can do it directly: Click Me No separate CSS file required ✅. 🔹 Benefits of the Utility-First Approach Speed ⏩ — You style as you go, no switching between HTML and CSS. Consistency 🎯 — Classes are standardized (e.g., px-4, text-lg). Customization 🎨 — You can extend colors, spacing, and themes easily. Responsive by Default 📱 — Mobile-first classes like md:, lg: make it simple. Example: Responsive Box This box changes padding and font size based on screen width. 🔹 A Real Example with React + Tailwind Tailwind Card This card is styled entirely with Tailwind’s utility classes. No custom 👉 Clean, reusable, and fully responsive. 🔹 Customizing Tailwind Tailwind is not just utilities — you can customize it in tailwind.config.js: export default { Then use it like: Brand Button 🎯 Final Thoughts Tailwind CSS shifts the way we think about styling: Instead of writing new CSS for each component, you compose with utilities. It’s faster, more consistent, and scalable for modern apps. If you haven’t tried it yet, spin up a project with Vite + Tailwind and see how quickly you can build beautiful UIs. ⚡ 👉 Do you prefer utility-first (Tailwind) or component-first (like Bootstrap/Material UI)?

You’re writing a simple Python function. It takes an item and adds it to a list, which defaults to an empty list if none is provided. It seems straightforward, but then this happens: def add_to_list(item, target=[]): # 🚨 This is the famous bug! target.append(item) return target list_1 = add_to_list('a') # Returns ['a'] list_2 = add_to_list('b') # Returns ['a', 'b']... wait, what? print(list_1 is list_2) # True - They're the same object! Why does list_2 remember the item from the first call? If you’ve encountered this, welcome to the club. This isn't a bug in your logic; it's a nuanced behavior in Python that has tripped up countless developers. Let's demystify it. The confusion stems from a critical point: Python evaluates default arguments only once—when the function is …  ( 8 min )

React is one of the most popular JavaScript libraries for building user interfaces. But when you combine it with TypeScript, you get type safety, better tooling, and fewer runtime errors. 🚀 If you’re just starting with React + TypeScript, this guide will help you set up your project and understand the basics. 🛠 1. Create a New React + TypeScript Project The easiest way is with Vite (fast and lightweight): npm create vite@latest my-app -- --template react-ts 👉 This sets up a React + TypeScript project instantly. 📦 2. Type Your Props In plain React, you might write: function Greeting(props) { Hello, {props.name}! ; } With TypeScript, we define the prop type: type GreetingProps = { function Greeting({ name, age }: GreetingProps) { (Age: ${age})} export default Greeting; ✅ Benefits: Autocomplete in your IDE Type checking at compile time No more “undefined” surprises 🔄 3. Using useState with Types Sometimes TypeScript can’t infer the state type. You can explicitly type it: import { useState } from "react"; function Counter() { return ( Count: {count} export default Counter; Here, useState(0) ensures count will always be a number. 🌍 4. Typing API Responses When fetching data, you can define an interface: type User = { async function fetchUsers(): Promise { https://jsonplaceholder.typicode.com/users"); Now whenever you use User, you’ll get intellisense + safety. 🎯 Final Thoughts React + TypeScript might feel like extra work at first, but the confidence and productivity you gain are worth it. Your IDE will catch bugs before they occur at runtime. Your codebase will be easier to maintain. Your teammates will thank you. 🙌 👉 Are you using TypeScript with React in your projects?

Introduction In Python, the reduce function is a powerful tool for performing cumulative operations on iterable data, such as lists or tuples. Instead of writing a loop to repeatedly apply a function to elements, reduce lets you “reduce” the iterable into a single value by successively combining elements. This makes your code more concise and functional in style. The reduce function is available in the functools module, so you must import it first: from functools import reduce reduce(function, iterable[, initializer]) Parameters: function: A function that takes two arguments and returns a single value. iterable: The sequence (list, tuple, etc.) to process. initializer (optional): A starting value. If provided, the reduction starts with this value; otherwise, the first item of the iterab…  ( 7 min )

Introduction Every developer has done it—hit Ctrl+C on a Stack Overflow snippet and dropped it into their project. It works instantly, deadlines are met, and life feels easier. But here’s the catch: those few saved minutes can plant the seeds of bugs, vulnerabilities, and technical debt that come back to haunt your future self (or your team). Let’s unpack why over-reliance on copy-paste coding isn’t as harmless as it looks. Speed over structure → deadlines push us toward shortcuts. Instant gratification → pasted code just works—until it doesn’t. Herd mentality → seeing snippets everywhere makes it feel acceptable. Copy-paste coding isn’t inherently bad, but the hidden cost usually shows up later. Each pasted snippet adds complexity you didn’t plan for. Maintaining multiple…  ( 7 min )

Have you ever introduced identical twins to your Python code, only to have it insist they're completely different people? Or worse, claimed two unrelated objects are the same just because they look alike? This common confusion stems from mixing up Python's is and == operators. Understanding the difference is a fundamental step toward writing correct and Pythonic code. At its core, the distinction is simple yet crucial: == (Equality): Checks if two objects have the same value. is (Identity): Checks if two variables point to the exact same object in memory. Think of it like this: == asks "Do you two look the same?" while is asks "Are you literally the same person?"

Composable Software in 2025: Building Systems Like Lego Software in 2025 looks very different from what it did a decade ago. The shift from monolithic applications to modular, composable systems has become the new norm. Instead of giant, all-in-one apps, businesses are increasingly adopting the “Lego approach” — building digital products from smaller, independent pieces that can be assembled, swapped, or scaled as needed. Think of composable software as digital Lego bricks: Want a new payment system? Swap out a block. Need advanced AI analytics? Plug in a new piece. Looking for faster deployment cycles? Break things into smaller parts and iterate independently. This flexibility allows businesses to stay agile in fast-changing markets while developers escape the headaches of ma…  ( 7 min )

We've all experienced it: you're in the process of working on a feature, and instead of writing a clean function or component, you simply round up something from one file and put it in another. It works... until it doesn't. Now you're debugging three different methods with almost identical logic. You start wondering, "Why didn't I make this reusable from the start?" Copy-pasting might save you a couple seconds today, but eventually, it's a snowball of technical debt. Writing reusable code is more than being "clean" or "fancy" — it's about making yourself (and your teammates) appreciate it in the future. In this article, I'll explain why reusability is important, how to actually do it, and show you examples you can take action on immediately. 🧩 Duplication of bugs – it takes you three tim…  ( 9 min )

Overview Today I had a simple idea: to recreate a CryEngine-era starter template island (it's strange that all those CryEngine goodies have vanished - otherwise I'd just link a YouTube video) in Godot, as a kind of inspirational playground. A modern equivalent would be something like this open-world landscape environment. The idea itself is straightforward: A 2 km x 2 km island Millions of trees (tall, short, and shrubs) An ocean A sky Creating the island itself was easy. The problem came when I tried instancing around 10,000 trees. Each tree mesh had about 240K faces, and even in Blender, instancing them with linked copies slowed the editor to a crawl (not surprising, though I had forgotten how slow Blender can get - that's why I once experimented with Clarisse). Importing that into Godot proved impossible: the .blend file was only 6 Mb, and the editor just hung. When comparing 5,000 MeshInstance3D objects with 5,000 instances in a MultiMeshInstance3D, the performance gain was minimal. This reminded me of a fundamental problem I'd almost forgotten: even if you reduce draw calls, fragment shading still happens, and rendering all those meshes at once causes severe overdraw. So, does this mean densely populated environments are not trivial in Godot? I do miss Unreal's shadow quality, but when it comes to large worlds, its automatic HLOD optimizations start to look tempting again. Then I remembered all the headaches with Nanite, Lumen, and other Unreal frustrations. Am I doomed? As it turns out, Godot does support HLOD, along with plenty of optimization options. Ultimately, everything depends on the purpose and final effect. There's no free lunch. This also highlights how little raw GPU processing power has advanced for single workloads - despite the massive petaflops of modern DGX systems, most of that is geared toward distributed or server-scale computing. If the goal is a stylized, large-scale world with detailed models but limited materials, Godot can probably handle it just fine.  ( 6 min )

You’ve embraced the cloud-native paradigm. Your microservices are elegantly containerized, your deployments are orchestrated by Kubernetes, and your infrastructure is defined as code. You’re doing everything right. But there’s a hydra in your cluster. For every secret you manage to secure—a database password, an API key—two more seem to take its place. You’ve encrypted them with SOPS, hidden them in Helm values, and tried to manage them with sealed secrets. Yet, you lie awake at night wondering: are our secrets truly secure? Are we compliant? How do we even rotate these things without causing an outage? If this sounds familiar, you’re not alone.

Change directory dot command If you are in a sqlite shell and forgot to change directory or want to navigate to a separate directory, you can do that with the .cd dot command. .cd /path/to/directory This is better than doing .shell cd /path/to/directory because it doesn't open a separate terminal process. So, the .cd is persistant throughout the session, whereas the .shell cd will only within that command (subprocess). The .cd command changes the working directory of the SQLite shell itself, so the change persists for the rest of the session. This means commands like .import, .read, or .output will automatically look for files in the new directory. However, .shell cd spawns a separate subprocess, and the directory change is discarded as soon as that command finishes. It does not affect SQLite’s own state of the current directory. So if you plan to read or write multiple files from a different location during your SQLite session, prefer the built-in .cd command.

Git is...complicated. This series focuses on breaking git down into commit-sized pieces. Git is a distributed version control system. Most of the time this isn't very relevant, because we usually work with a single, central repository, but we don't have to. Because we clone the whole repo to our computers, each copy contains everything. Unlike centralized version control, you don't have to stop collaborating when the server goes down. You can still sync and share and merge work directly with other developers, whether there's an outage or you are working in an environment without Internet access. This disconnect from "traditional" centralized version control systems dating back to the 1960s can be hard to grasp, as git isn't like most of our models of servers we connect to. We download and…  ( 7 min )

AI coding assistants like ChatGPT are everywhere now. They can scaffold components, generate test cases, and even debug code. But here’s the catch: they’re not senior engineers. They don’t have context of your project history, and they don’t automatically spot when the tests themselves are wrong. In other words: treat ChatGPT like a junior dev on your team — helpful, but always needing review. I was recently working on a legacy React form validation feature. The requirements were simple: Validate name, email, employee ID, and joining date. Show error messages until inputs are valid. Enable submit only when everything passes. The tricky part? I didn’t just have to implement the form — I had to make it pass an existing test suite that had been written years ago. I turned to ChatGPT …  ( 8 min )

Step by Step Workflow of Traffic from NAT Gateway to Internet Note: This post was originally published on my main blog site. If you’ve ever launched an EC2 instance in a private subnet, you’ll notice it can’t reach the internet. But what if your instance needs to connect to external services while still staying private and hidden from the public internet? That’s where a NAT Gateway comes in. A NAT Gateway allows private resources to securely access the internet without being exposed to it. It’s simple to set up, but many AWS engineers get confused about how the traffic actually flows. From an EC2 instance, through the NAT Gateway, and out to the internet. In this blog, we’ll walk through the step-by-step workflow of how an EC2 instance in a private subnet reaches the internet.

The Challenge: Moving Beyond Cloud Dependencies (And My Hatred of Making Slides) Let me be honest - this project started because I absolutely despise creating PowerPoint presentations. The tedious process of outlining content, formatting slides, finding relevant images, and making everything look professional drives me crazy. I'd rather spend hours coding than 30 minutes making slides. So naturally, I thought: "What if I could just talk to a device and have it generate the entire presentation for me?" But here's where it gets interesting. Most AI applications today rely on cloud inference - sending data to remote servers, waiting for responses, and dealing with latency, costs, and privacy concerns. I wanted to explore whether modern edge hardware could handle something more ambitious: a …  ( 11 min )

Hey everyone, I’m Amir from Norway. Over the past years working in energy tech, I’ve noticed something frustrating: every digital energy project reinvents the same building blocks. Whether it’s solar, EV charging, or smart buildings, people keep writing the same connectors, data pipelines, and forecasting models — but in silos. We don’t have to keep doing this... That’s why I and my co-founders started Qubit Foundation; an open-source project where developers, researchers, and companies etc, can collaborate on the shared foundation for the future of energy. Here’s the vision we want to achieve: Modular, interoperable services → like LEGO blocks (data schemas, connectors, forecasting, optimization, APIs). Universal standards → so energy systems can actually talk to each other. Community-driven → open collaboration, not closed silos. Why join? Be among the first contributors — basically the “founding members” of this project. Help shape how we build out repos, services, and architecture. Work on tech that actually matters for the climate and energy transition. We aim to grow into something global: with sponsors, hackathons, and even gatherings. We’re just kicking off, if this resonates with you, check out our repos and additional links below https://github.com/qubit-foundation https://docs.qubit.energy/introduction) https://foundation.qubit.energy Let’s help humanity achieve sustainability, starting by accelerating the movement towards clean energy.

Big news dropped last week that nobody's really talking about: Anthropic launched the Model Context Protocol (MCP) Registry—an open catalog and API for publicly available MCP servers. Finally, right? Or... is it? The MCP Registry is now available at https://registry.modelcontextprotocol.io as the official MCP Registry. Think of it as npm for MCP servers - a centralized place to discover, publish, and manage MCP servers. The tech is solid: Open source with OpenAPI spec Namespace system (io.github.yourname/* or com.yourcompany/*) Integration with existing package managers (npm, PyPI, Docker Hub) Sub-registry support for companies building their own marketplaces 1.

We've probably all had this dream of waking up in the morning and finding ourselves with 10,000 new users on our platform. (At least as a Co-Founder & CTO, that's the dream) 😁 So we asked ourselves: can we run a dedicated environment of our platform entirely on nanos? Spoiler: it worked, and it taught us a lot about where our real inefficiencies were hiding. Here are some of these learnings: The Reality of Scaling: When your startup does grow and you start scaling your infrastructure, what really happens? Often it turns out that: Important indexes are missing, leading to CPU spikes. Query results are loaded into memory without paging, causing out-of-memory errors. Other inefficiencies appear that raw cloud scaling alone cannot solve. The result is often not a sleek, hyper-scalable system …  ( 7 min )

Introduction to Amazon S3 – The Backbone of Cloud Storage Every day, organizations generate massive amounts of data — from user activity logs, application files, and backups to videos and images. Managing this data securely and cost-effectively is a big challenge. This is where Amazon Simple Storage Service (Amazon S3) comes in. It’s one of the most popular cloud storage services in the world and a core building block for anyone preparing for AWS Data Engineering certifications. In this blog, we’ll break down what S3 is, why it’s important, and how it works with simple examples. Before cloud storage, companies stored data on local hard drives or on-premise servers. Limited capacity (1TB–2TB hard disks at most for personal PCs). High costs for scaling. Hard to share or access remotely. Data…  ( 7 min )

If you’re just starting to learn coding, two things you’ll always hear about are variables and data types. Don’t worry, they sound more complicated than they really are! Let’s break them down in a way that makes sense. A variable is like a name tag on a storage box where you can keep data. You can store a number, a word, or even a list of items. And the cool part? You can change what’s inside whenever you want. For example, let’s say you want to keep track of your age and name. You could write (in Python): age = 26 Now, age and name are variables holding values. You can change them: age = 23 Now, let’s talk about data types. Think of data types as categories or labels for the different kinds of data you can store. Not everything can go into every variable. Some data is numbers, some is tex…  ( 7 min )

The Model Context Protocol (MCP) is emerging as a foundational interface for new types of AI-driven interactions, where intelligent agents act as a new kind of user, or persona. Just as businesses meticulously design web UIs and REST APIs for human users and third-party integrations, they now have the opportunity to design the perfect "agentic experience" for these autonomous entities. The primary objective is to maximize the task completion rate, which is the ability for an MCP client with its underlying model to successfully complete a user-given task. This article explores the challenges and best practices for achieving this efficiency, with a focus on measurement, design patterns, and operational pitfalls. Measuring an MCP server's efficiency is a complex undertaking. The ideal metric,…  ( 11 min )

Hi! My name is Augusta👋 I’m new here on dev.to. I’m a student of Electronics and Computer Engineering. Right now, I’m learning web development — the usual HTML, CSS, and JavaScript. I’ve taken some courses, but I noticed that after each tutorial I would just move on to the next one. So I’ve decided to switch things up and focus on building projects. After all, what better way to learn than by actually creating something? I’ve realized that I understand concepts more deeply when I have a reason to use them in a real project. That’s why I started a Udemy course: 50 Projects in 50 Days. I’ll be posting about some of these projects here: what I practiced what I learned and the mistakes I made along the way I may not write about all 50 projects, but I plan to share at least one project a week until I finish the challenge.

We talk a lot about AI agents in crypto, but most projects so far feel like hype with limited real deployment. Recently, I read about Talos, a protocol experimenting with an AI-governed treasury system that runs on Ethereum, now integrated with Oasis’ Runtime Off-chain Logic (ROFL). Thought I’d break it down from a builder’s perspective. What is Talos? Talos is essentially an AI-powered asset manager on-chain. It rebalances a treasury of yield-bearing assets (think lending, liquidity pools, derivatives) based on signals it pulls from markets, social data, and on-chain activity. Underneath, it uses ERC-4626 vaults with ETH as the base unit for conversions. The interesting part: Talos isn’t fully autonomous. It’s paired with a governance model where humans (via the Talos Council) oversee strategic decisions. Think of it like an AI portfolio manager with a human “board of directors.” Key Components Governance Hybrid:AI executes day-to-day, but council votes are needed for critical strategy changes. This balances automation with accountability. Risks & Open Questions Model risk: AI strategies can still be gamed or misled by bad data. Why Developers Should Care Shows a real use case for combining AI agents with confidential compute + on-chain proofs. Final Thoughts Talos feels less like vaporware and more like a sandbox for exploring AI-on-chain governance. If it holds up under market stress, it could pave the way for agents that handle execution while humans steer strategy. For devs interested in AI + DeFi, I think this is one to keep an eye on. 👉 Full blog here: Talos: On-Chain Intelligence with ROFL  ( 7 min )

Last week, a significant supply chain attack hit the JavaScript/TypeScript ecosystem through the npm registry. Multiple widely used packages, collectively downloaded more than 2 billion times per week, were compromised via a single maintainer’s npm account. Malicious versions of debug, chalk, ansi-styles, and 15 other packages were published. The payload focused on stealing cryptocurrency wallets, but the incident underscored a broader, ongoing risk: the open source supply chain is a high-value target. And it didn’t stop there. This week, another campaign dubbed "Shai-Hulud" targeted additional npm packages, this time exfiltrating sensitive data and attempting self-propagation across the ecosystem. Plenty has already been written about these attacks. Here, I’ll focus on the impact on the M…  ( 8 min )

Prompt engineering is becoming a must-have skill for developers working with AI models like ChatGPT, Claude, Gemini, and others. But writing good prompts isn’t just about asking questions — it’s about structuring your intent so the model gives you exactly what you need. Two frameworks that help with this are Prompt TAG and Prompt RISE. Let’s break them down, understand when to use each, and look at real examples. TAG stands for: T = Task: What you want the model to do. A = Audience: Who the response is for. G = Goal: What outcome you expect. This framework is great for quick, focused prompts — especially when you want the model to adapt its tone or depth based on the audience.

By Iyanuoluwa Faleye Design patterns are a collection of standard solutions to solve software development design problems. Software engineers need to know how to use design patterns as essential tools. They can utilize design patterns to discover elegant solutions for commonly occurring challenges in software design, just as architects in building architecture learn to address design difficulties using established patterns. The efficiency, scalability, and readability of code are all improved by comprehending and utilizing these patterns. The three categories that these patterns fall into are creational, behavioural, and structural. To keep things brief, we’ll define these categories and explore examples that fall into these categories over a series. Creational Pattern: These patterns addr…  ( 8 min )

DbSchema lets you split a big schema into smaller diagrams. one diagram for Orders & Transactions, another for Customers & Billing, one more for HR. The database is the same, but you look only at the part you need. Most projects don’t have only one database. In DbSchema, you can save all connections in the same project and switch between them easily. Example: company_dev company_stage company_prod One click, and you are connected to the right place. Changing a big schema is stressful. ALTER TABLE directly in production, do it step by step: Change the table visually in the diagram. Use Schema Compare to see what changed between the model and the database. Le…  ( 7 min )

Deploying a CNN-BiLSTM Model on AWS Lambda Deploying my deep learning model to production sounded straightforward at first. I had a Convolutional Neural Network + Bidirectional LSTM (CNN-BiLSTM) model for EEG-based Alzheimer’s detection, and I wanted to expose it via a serverless API on AWS. Before going into the mistakes, let’s briefly discuss the deep learning model. It combines CNN and BiLSTM for Alzheimers’ detection based on EEG data. Now this app lets users upload EEG .set files and get an Alzheimers’, Frontotemporal dementia, and Healthy prediction with a confidence score. Uploaded files go directly to S3, and then a serverless Lambda (containerized with TensorFlow + MNE) pulls that file, preprocesses it, runs inference, and returns JSON to the browser. The user uploads the EEG f…  ( 10 min )

When I first started learning React, I used Create React App (CRA) — because that’s what everyone recommended. But after trying Vite, I knew there was no going back. Here’s why I made the switch. CRA: Takes ~20–30 seconds to start. Vite: Starts in less than 1 second. That difference is massive. When you restart your server multiple times a day, those seconds add up and slow you down. Vite feels instant — you save time and stay in the flow. With CRA, I’ve experienced times where hot reload just… stops working, and I had to refresh manually. Vite’s hot module replacement (HMR) is consistently fast and reliable — every save gives instant feedback. It sounds small, but it completely changes how fast you can iterate. CRA hides a lot of config behind react-scripts. If you want to tweak Webpack, you have to eject, which makes things messy and hard to maintain. Vite uses Rollup under the hood and has a clean, minimal config that’s easy to extend. Vite uses native ES modules for development and supports the latest JS features out of the box. No heavy build step during dev — just fast, modern tooling. Feature CRA Vite Dev Server Start ~20–30s (Webpack) < 1s (esbuild) Hot Reload Sometimes Lags Instant & Smooth Config Eject Required Minimal Setup Developer Experience Slower Workflow Fast & Enjoyable npm create vite@latest my-app cd my-app npm install npm run dev Boom — you’re up and running in seconds. If you’re still using CRA for new projects, I’d highly recommend trying Vite. The difference in speed and developer experience is hard to ignore. What about you — have you switched yet? Drop your thoughts below, I’d love to hear how your experience compares.  ( 6 min )

When I first tried AI coding, I was bored out of my mind. I’d type in a prompt… and think ‘guess I’ll wait?’ A minute later, some half-baked code would appear. I’d ask for a refactor. More waiting. Another tweak. More waiting. Eventually I’d close the tab and move on. The hype told us AI would be like waving a wand: type a prompt, get production-ready code. So when the output is clumsy, we don’t ask ‘What did I miss?’—we jump straight to ‘This thing is dumb.’ You’re not alone if you’ve felt that way—nearly half of developers don’t trust AI’s accuracy according to the 2025 Stack Overflow Survey. Here’s the shift: AI isn’t magic. It’s a tool. And tools only become powerful once you learn how to use them.

Long meetings aren’t just annoying-they’re expensive. A few subtle mechanics can turn drift into decisions and make on-time finishes the default. Unbounded discussion crowds out priority work. Decisions happen late, or not at all-so work starts late. People leave unclear, so follow-ups multiply. Small overtime nudges are enough to prevent runaway calls. With Minute Minder in Google Meet, the timer shifts color for “5 minutes left” and Overtime. You can add a soft chime if your team likes audio cues. This is a polite heads-up: the room sees it, feels it, and moves. Try this: Make a team norm: overtime cues = decide or park. At “5 left,” choose: decide → assign → or park. If still talking at Overtime, stop new topics. Switch to Wrap in 2 (owner + date). At T-2, speak your summary first: Decision(s): What did we choose? Owners & dates: Who does what by when? Parking lot: What got moved and who owns it? Paste the bullets into chat (or your notes) before closing the tab. Minute Minder’s wrap-up prompt makes this automatic. Before: 55 minutes, spill-over discussions, unclear owners. After: Timer visible; “5 left” triggers decisions; overtime color shows → two items parked; T-2 wrap assigns owners. Result: Shorter call, clearer ownership, fewer follow-ups. Try Minute Minder on your next two sprints. The visible timer and overtime cues will help you land the plane on time-and turn meetings into decisions, not drift.

The concept of work-life balance has become increasingly important yet paradoxically elusive. As a developer who runs a bespoke web development agency, I understand the challenges that come with the territory - tight deadlines, demanding clients, and the ever-present temptation to check your email just one more time before bed. However, I also recognize the critical importance of maintaining equilibrium between professional commitments and personal well-being. Here's a pragmatic guide on how both individuals and organizations can foster a healthier work-life balance. First and foremost, setting boundaries is essential.

“Why do I have to update tens of thousands of rows every time, when all I want is to reorder tasks a little?” — Are you tired of this kind of database design?

Most calls run long for two simple reasons: time is invisible and transitions are vague. This playbook makes time visible, keeps momentum, and lands the plane without anyone feeling policed. No shared sense of pace → topics sprawl. Decisions come late → the ending creeps past the calendar. “One more thing” appears when nobody can see the clock. Time-boxing replaces guesswork with gentle, visible boundaries. When everyone can see the minutes, scope naturally shrinks to fit. Try this: For any meeting >15 minutes, draft the agenda as segments with buffers before you add invitees. Suggested flow 00:00-03:00: Goal & success criteria 03:00-20:00: Topics (2-3 segments) 20:00-28:00: Decisions & owners 28:00-30:00: Wrap + follow-ups Keep a visible timer on-screen in Google Meet. With Minute Minder (a lightweight, privacy-respecting Chrome extension), you can show a countdown or elapsed timer as a small overlay so everyone senses the pace without breaking flow. Add soft cues at halftime and “5 minutes left” to keep transitions smooth. (There are overtime alerts and an end-of-call wrap-up prompt too.) Try this: Add a 2-3 minute buffer to the last topic. If unused, you’ll finish early (high-trust win). Split big topics into 7-12 minute chunks. Name the desired outcome for each segment (approve, decide, delegate). Buffer every second segment by 1-2 minutes. Minute Minder lets you seed checkpoints like “Halftime,” “Decision time,” and “Wrap in 2”. These appear as polite on-screen nudges (with optional gentle chimes) rather than interruptions. Halftime: summarize and move if needed. Decision time: push outcome language (“Approve A, ship B by Tues”). Wrap in 2: switch the room to action owners and dates. Get Free Chrome Extension: https://minuteminder.io/  ( 6 min )

Recently, I was writing a module with multiple APIs for a new project. I started with the fundamental API. The team had multiple rounds of discussions. I put in hours writing code, testing, and debugging. When I raised the PR, it went through rigorous reviews (as it happens with any new functionality module), until finally the changes were merged and deployed. But in the next meeting with the Business team, we realized that we missed a major point in the earlier discussions. And one missed point translated into reworking the whole API from scratch. It became clear that without a structured approach, we risked falling into the same cycle of rework again. The solution that saved us was documentation. The functionality was complex and difficult to grasp at once, and therefore, there's a hig…  ( 7 min )

Aaaand she's here! Last time, we created the rules/grammar basis which the parser converts tokens into syntax-tree. Now, we create association rules, i.e. we define the order in which expressions must be parsed to generate the tree. Recursive descent parsing is used here, wherein the parser starts from the outermost/top-level rule with lowest precedence and traverses through subexpressions to make it to the tree's bottom, where it finds literals (which happen to have the highest precedence). What I built: Commit 5750470 What I understood: Association Rules The rules we create must be defined as functions which call other functions of higher precedence, until we reach literals.

Yet many developers find themselves frustrated when the AI produces vague, irrelevant, or simply wrong answers. The problem isn’t always the AI — it’s often the prompt.

In this blog, we’ll explore how to craft prompts that get you better, faster, and more reliable results. LLMs don’t “think” like humans. They generate responses based on probability and context. A well-written prompt provides: Clarity – reduces ambiguity. Context – gives the AI background knowledge. Constraints – keeps answers focused. …  ( 7 min )

Seriously, can you even imagine life without your phone these days? Apps run everything — from your bank account to your pizza order to that weird step counter you swear by. Businesses? Oh, they’re even more hooked. But here’s the thing — while we’re all tapping away, hackers are out there plotting ways to mess things up. That’s where mobile app pen testing comes into play. And no, it’s not about poking your phone with a pen. Basically, pen testing (yeah, short for penetration testing, but who actually says the whole thing?) is like hiring someone to break into your app just to see how easy it is. The idea? Find those weak spots before the real bad guys do. When it comes to mobile apps, this kind of testing is a lifesaver. It helps spot security screw-ups, keeps your data from leaking all …  ( 10 min )

For over a decade, Ngrok has been the standard choice for developers who need to expose a local service to the internet. Whether you’re testing webhooks, demoing an app for a client, or running a quick experiment, Ngrok provides a fast way to create secure tunnels. It comes with a powerful set of features—support for HTTP, TCP, and TLS tunnels, request inspection, and authentication methods like OAuth and JWT. But Ngrok isn’t always the perfect fit. Some developers find the setup too heavy for quick experiments, others run into bandwidth caps, and many simply want something more affordable. As a result, a number of alternatives have emerged, each with its own philosophy: some aim for simplicity, others for flexibility, and a few lean into open-source and self-hosted models. Here are five a…  ( 9 min )

The Internet of Things (IoT) has moved beyond being a futuristic idea—it is now part of our everyday lives. From smart homes and wearable devices to connected factories and smart cities, IoT is shaping the way businesses and people operate. However, as industries adopt IoT at different scales, one challenge keeps coming up: how to manage all kinds of devices on one unified platform. This is where the idea of a future-proof IoT platform comes in—one system that works for every device, across every industry. Why IoT Needs a Unified Platform Different industries rely on very different IoT devices: Healthcare uses wearables, remote patient monitors, and smart hospital equipment. Manufacturing depends on asset trackers, machine sensors, and predictive maintenance tools. Retail uses smart shelve…  ( 8 min )

Data Integration Dilemma in the Multi-cloud Environment ● Failure to discover new files in a timely manner Cloud file system providers typically only provide Bucket traversal interfaces, but are unable to traverse newly added files in chronological order. Therefore, when the number of files in a single Bucket exceeds hundreds of millions, efficiently identifying new files without significantly prolonging the subsequent process becomes the primary challenge faced by developers engaged in multi-cloud file data integration. ● Need for elastic scaling The business volume of an enterprise often fluctuates periodically, and accordingly, the log volume changes. The log file size may vary significantly in the peak and off-peak hours. If the elastic scaling of resources fails, the following problem…  ( 15 min )

You learn by comparing to what you already know. I was recently bitten by assuming Rust worked as Java regarding transitive dependency version resolution. In this post, I want to compare the two. Before diving into the specifics of each stack, let's describe the domain and the problems that come with it. When developing any project above Hello World level, chances are you'll face problems that others have faced before. If the problem is widespread, the probability is high that somebody was kind and civic-minded enough to have packaged the code that solves it, for others to re-use. Now you can use the package and focus on solving your core problem. It's how industry builds most projects today, even if it brings other problems: you sit on the shoulders of giants.

Why this matters As DevOps engineers, we often automate deployments — but how do we verify that the new build actually reached the server? Instead of logging in manually every time, we can use a small shell script to automate this check. 🖥️ The Shell Script APP_URL="http://your-server-ip:8080/health" DEPLOYED_VERSION=$(curl -s $APP_URL | grep "version" | cut -d '"' -f4) if [ "$DEPLOYED_VERSION" == "$EXPECTED_VERSION" ]; then 📌 How it works 1.Define the server endpoint (e.g., /health, /version, or your API’s status endpoint). 2.Use curl to fetch the response. 3.Extract the build/version info. 4.Compare it with the expected version. 🧪 Sample Output If deployment succeeded: ✅ Build 1.0.0 is deployed successfully! If deployment failed: ❌ Build not deployed. Found version: 1.2.2 🚀 Takeaway With just a few lines of Bash, you can automatically check whether your build has been deployed correctly. This script can even be added to your CI/CD pipeline as a post-deploy verification step. 💬 What about you? 👉 How do you verify your deployments today — manual check or automated script?  ( 6 min )

The CLI (command-line) tool Repository-Context-Packager was built to analyze local git repositories and create a text file containing repository content optimized for sharing with LLMs (Large Language Models). Below are the features implemented in this project: Command Line Entry Point: I used the Commander.js library to handle commands, arguments and options. Output Formatting: I implemented a buildTree() utility function to create a text-based tree structure of directories and files. This took me sometime to be able to have a nice tree representation. The current Git commit information was included as well as a summary showing the total number of files and lines processed. File Reading and Exclusions: Some of my files like package-lock.json were over 16KB, so I had to truncate it with a note specifying the user that only the first 16KB have been included. I also excluded files like node_modules, .git. Optional Features: I integrated the .gitignore where I listed some files to be automatically excluded. I also implemented options like --output to write to a file, and --include to filter file types by extension. I am really happy with what I have built so far. It is not perfect, can still be improved but it is satisfying to see the little things we can learn each day. This first open source project enhanced my understanding of working in open source with other people, reviewing issues, fixing and closing them. I gained a lot and enhanced my knowledge on GitHub. With this tool, I can now package a repository and send it to an LLM for help in seconds, hence no more copy-pasting files one by one which is time saving.

⚔️ TCJSgame v2 vs v3 — Accurate comparison, code diffs, and ratings If you've been working with TCJSgame, you probably use v2 and are testing or migrating to v3. I dug into the actual v2 code and compared it to v3 changes. This article shows what changed, why it matters, and gives a numeric rating (out of 100) for each version across features, ease of use, and performance. v2 is simple, compact, and easy to learn — excellent for small demos and prototypes. v3 adds camera support, tilemaps, sprites, angle-based movement, and better utilities — a step toward a proper 2D engine. Recommendation: For new projects start with v3. For tiny demos or compatibility needs, v2 still works. v2 Uses setInterval(() => this.updat(), 20) (~50 FPS). Movement is pixels per frame, not time-based. v3 …  ( 8 min )

When Curiosity Lead the Way If you have been in software development for a while, you might remember a time when developers were launching unique and innovative products and projects just for the sake of curiosity, learning or even just because they had a particular interest in a specific topic. This curiosity and problem solving mindset gave us some of the best tools that we still use today such as VLC, Linux, Git, Apache HTTP Server, Docker(arguably), and many many more. These tools were not created by large corporations or solopreneurs looking to increase their MMR or ARR. They were created by curious developers who wanted to solve a unique problem they had or even just wanted to learn something new.

Most engineers who’ve worked with AWS Cloud will have launched an EC2 instance (a virtual machine). But only a few of them really know what the “3/3 checks passed” message on the console actually means. This post explains what these status checks are, why they matter, and what you should do if one of them fails. This is also something that might come up in an cloud interview question 👀. When an instance is launched or started, AWS runs three types of status checks: System Status Check Instance Status Check Instance Reachability Check Let’s go through each in detail. 1. System Status Check ✅ What it checks: The AWS infrastructure hosting your instance — hardware, networking, and power. Stop & start your instance (it will migrate to a new host). If the issue persists, you should probably speak to aws support team through raising a support ticket. 2. Instance Status Check ✅ What it checks: Your instance’s operating system( kernel, boot process, responsiveness). Check system logs in the EC2 console. Use EC2 Serial Console or SSM Session Manager if SSH/RDP isn’t working. Fix issues like kernel panics, misconfigured filesystems, or firewall lockouts. Reboot after fixing. 3. Reachability Check ✅ What it checks: Whether the instance is accessible over the network (SSH, RDP, or service ports). Check security group rules and NACLs(basically you will have to check whether you have created the instance in right subnet with right routes) Confirm route tables & internet gateway for public subnets. Verify the instance firewall (ufw, iptables, Windows Firewall). Think of it this way - if your EC2 instance passes all three checks, it’s like your VM just cleared a cloud-level health checkup. Green lights all the way means you can focus on building, not babysitting. Until next time, Saiyonara. 👋  ( 7 min )

The year 2025 marks a pivotal moment for quantum computing. What once existed solely in research laboratories is now solving real-world problems across industries. From financial institutions optimizing investment portfolios to pharmaceutical companies accelerating drug discovery, quantum computing is transitioning from theoretical possibility to practical reality. Traditional computers use bits that exist as either 0 or 1. Quantum computers use quantum bits, or qubits, which can exist in multiple states simultaneously through superposition. This allows quantum systems to explore many possible solutions at once rather than testing each one individually. Several major companies are already implementing quantum computing for data-intensive operations. JPMorgan Chase and Goldman Sachs use qua…  ( 10 min )

In the era of large language models (LLMs), the way we interface with Al has fundamentally changed. Instead of coding algorithms line by line, we now shape Al behaviour through prompts - a seemingly simple, but incredibly powerful interface. Whether you're a ML engineer deploying custom GPT-4 apps or a data scientist experimenting with LLAMA 2, you're likely to engage in some form of prompt design. In the rapidly evolving landscape of LLM customisation, two major approaches stand out: Prompt Engineering and Prompt Tuning. Both promise to optimise Al performance but they operate on different ends of the spectrum. So the real question is: where does the true power lie? What is Prompt Engineering?

As developers, we rely on MySQL for dependable access to data. When the error “MySQL Shutdown Unexpectedly” appears, applications relying on it grind to a halt. The lack of clear details in the message only adds to the challenge. The good news is that this isn’t an unknown bug. It’s a symptom of specific, repeatable issues that are well-documented and solvable with a methodical approach. By narrowing down possible causes — from service problems to corrupted files — you can bring MySQL back online without unnecessary delays. Config missteps: Memory allocations that exceed system resources. Stopped service: MySQL not restarted after being manually stopped. Port conflicts: Another process using port 3306 or 3307. Permissions: Running MySQL without admin rights on Windows. Corruption: InnoDB log or data files out of sync. Restart the service to confirm MySQL is active. Reduce buffer/memory allocations in your config file. Check port usage with: netstat -ano | findstr 3306 Run the service with administrator rights on Windows. If corruption is suspected, remove ib_logfile* after backup and restart. It usually comes down to oversized settings, blocked ports, or corrupted files. Sometimes it’s simply that the service was never restarted. Optimize queries with indexes, partition large datasets, and monitor schema performance. Security practices also help keep databases stable. It supports over 50 databases and offers tools for analyzing queries, indexes, and schemas.

Entrepreneurship is all about taking risks, experimenting, and learning from every step you take. Every successful startup you see today began with a single small action, a single idea that someone dared to pursue. The journey of an entrepreneur is rarely smooth. There will be challenges, failures, and moments of doubt. But the key is to start somewhere. Even small actions, like conducting market research, networking with mentors, or building a simple prototype, can set the foundation for something bigger. For students and aspiring entrepreneurs, it’s important to embrace the mindset of action. Don’t wait for the perfect idea, perfect team, or perfect time. Start now, iterate often, and keep learning. At E-Cell, IIT Bombay, we believe in creating job creators, not just job seekers. By taking small steps every week, learning from our experiences, and sharing knowledge, we are building a strong ecosystem of innovation and entrepreneurship. 💡 Tip: Start small, stay consistent, and don’t fear failure. Every big achievement begins with a single courageous step. Conclusion: Remember, your first action doesn’t have to be perfect. Start, learn, iterate, and grow.

Mac patch management is the process of monitoring, deploying, and verifying updates for both the macOS operating system and the applications running on it. Done well, patch management reduces vulnerabilities, minimizes downtime, and ensures IT teams can keep fleets of Macs aligned with organizational policies. If you own a Mac, you know that updates pop up regularly. For an individual user, hitting “Install Now” is usually enough. But in a workplace with dozens or hundreds of Macs, updates can be a lot more complicated. Some updates fix security problems, others add new features, and some arrive unexpectedly. If every Mac installs them at different times, IT teams can lose track of who’s protected and who isn’t. Even worse, a single unpatched computer could put the whole company at risk. I…  ( 9 min )

A consumer needs an offset (a bookmark) to know where to start reading from a partition. Normally: Kafka stores the last committed offset in _consumer_offsets. When you restart a consumer, it resumes from that committed offset. But… what if there is no valid offset for a partition? auto.offset.reset kicks in. New consumer group (first time this group subscribes to a topic → no committed offsets exist yet). Offsets got deleted (Kafka has a retention policy for committed offsets — e.g., offsets.retention.minutes). Offset is invalid (maybe pointing to data that was deleted due to log retention). Start reading from the beginning of the log (smallest available offset). Consumer will replay all historical data. Good for batch jobs, data pipelines, or when you really want everything (e.g., reindexing a search database). Start reading from the end of the log (largest offset). Consumer ignores past data → only gets new messages arriving after it joined. Good for real-time dashboards or monitoring, where you don’t care about history. If you forget this setting, you can accidentally replay millions of messages when you didn’t intend to. Conversely, you might miss data if you start from latest in a system that needs history.  ( 6 min )

In this era of Artificial Intelligence, the humanitarian sector can no longer afford to sit on the sidelines. Automation, once seen as a luxury, is now a lifeline. It’s the quiet miracle helping aid organizations streamline operations, reduce errors, and free up precious time for what truly matters,serving communities in crisis. Let’s take a closer look at how automation is already making a difference across five critical areas. Donor Reporting and Compliance For many humanitarian organizations, the end of the year brings a whirlwind of donor reports, compliance reviews, and impact documentation. In 2025, this workload has intensified, especially following funding reductions from USAID. NGOs have found themselves submitting more frequent reports, crafting detailed justifications for grant …  ( 7 min )

Learn how to implement soft deletes in Prisma, avoid common pitfalls, and keep those ghost records under control. It was just another regular day at the office. I was staring at a database schema, plotting out a shiny new feature, when my phone buzzed. One of the guys from the support team was on the line. Apparently, a customer had accidentally deleted a few records through the application UI and now wanted to know the answer to the million-dollar question: “Can you get them back?” The answer, of course, was the soul-crushing, developer-standard “No.” So, the poor customer had to recreate those records from scratch. And me? I couldn’t stop thinking, there had to be a better way. Sure, the obvious answer was to restore from a backup. But let’s be real: digging through backups just to fish …  ( 16 min )

In today’s hyper-connected world, our devices are not just gateways to the internet—they are part of the internet itself. Search engines like ZoomEye, sometimes called the "Google for cyberspace," are designed to scan and index internet-connected devices around the globe. This visibility raises an important question: Why might your home router, security camera, or even smart refrigerator appear in such a search engine? ZoomEye is a cyberspace search engine that continuously scans the internet to identify devices, open ports, and services. Security researchers often use it to: Map the global landscape of internet-connected devices. Track trends in exposed services and protocols. Understand security risks in IoT and industrial systems. Unlike traditional search engines that index web pages,…  ( 7 min )

Executive Summary “Getting more done at the same time” sounds efficient – but it isn’t. Cognitive psychology has shown for decades: true simultaneity of complex tasks is practically impossible. Instead, what happens is task switching, which carries measurable costs in time, quality, and stress. Those who reduce distractions, work in clear blocks, and make work visible (e.g., with TimeSpin) significantly improve output and well-being. Key findings: switching costs per context change, a central psychological bottleneck in dual tasks, and significantly increased error and reaction times (e.g., when talking on the phone while driving). Our brain does not execute complex tasks in parallel. When switching between activities, executive control processes are engaged: Goal shifting – shifti…  ( 8 min )

There’s a quiet moral tension hanging over much of the federal contracting community these days – a sort of collective soul-searching we don’t always name out loud. Many of us are caught in a Catch-22: we dedicate our careers to supporting federal programs that improve lives, strengthen national security, and serve communities. Yet, under the current administration, some of those same institutions feel misaligned with the values we hold dear. There’s a sense that by continuing to work in this space, we’re complicit (or at least complicit-adjacent) in policies or rhetoric that may undermine equity, justice, or truth. The paradox is painful. We question whether we’re compromising our principles for a paycheck. We whisper about feeling like we’re selling our souls just to keep the lights on. And still, we show up. We staff the programs. We write the proposals. We deliver the services. Because here’s the truth: behind every contract is a mission. Behind every mission are people – military families, underserved communities, public servants, veterans, students, scientists – depending on the systems we help build and sustain. We’re not serving a party. We’re serving a nation. The machinery of government may sometimes feel broken, but the purpose behind it is not. It’s in the resilience of a public health program. In the innovation behind a new defense capability. In the reach of a grant-funded nonprofit working in forgotten corners of the country. Yes, it can feel dark right now. Cynicism comes easy. But purpose still exists in this work if we remember who we’re really doing it for. We don’t have to agree with every decision from the top to continue making a difference where we can. If anything it’s in these moments, when the headlines feel most discouraging, that we’re needed most. So, we navigate the paradox. We hold on to our integrity. And we keep going. Not in spite of our values but because of them.  ( 6 min )

JavaScript Scope Explained: Your Ultimate Guide to, Functions, and Closures If you've ever written a JavaScript function and found yourself asking, "Why can't I access this variable here?", or if terms like "closure" and "hoisting" make you feel a little uneasy, you're not alone. Understanding scope is one of the most fundamental and, at times, most confusing aspects of learning JavaScript. But here's the good news: once you truly grasp scope, a whole world of JavaScript clarity opens up. You'll write more predictable, efficient, and powerful code. You'll finally understand how and why your code works, rather than just that it works. This guide is designed to be your comprehensive, start-to-finish resource on JavaScript scope.

The mobile gaming industry has always thrived on cultural moments. From the early days of Flappy Bird in 2013 to the rise of Among Us during the pandemic, viral trends have consistently reshaped how games are discovered and consumed. In 2025, the TikTok-driven “Italian Brainrot” phenomenon has become the latest and perhaps most unusual case study of turning decade-old hyper-casual games into global chart-toppers. For developers, this isn’t just a passing fad; it’s a blueprint for how internet culture can redefine growth strategies. At its core, “Italian Brainrot” is a surreal meme wave born out of TikTok’s remix culture. Users layered bizarre AI-generated characters with repetitive Italian audio snippets, creating viral loops that spread across platforms. What began as satire about wast…  ( 8 min )

JavaScript Errors: Your Ultimate Guide to Taming the Red Text There it is. You’ve been coding for an hour, feeling like a digital wizard, and you hit refresh.

Beyond Break: Mastering the JavaScript Continue Statement for Cleaner, Smarter Loops Welcome, fellow coders! If you've been writing JavaScript for even a little while, you're intimately familiar with loops. for, while, do...while – these are the workhorses that allow us to automate repetitive tasks, process arrays, and navigate complex data structures. You've probably also met break, the trusty command that lets you exit a loop entirely when a condition is met. But today, we're going to shine a spotlight on its often-overlooked yet incredibly powerful sibling: the continue statement. While break is the emergency exit, continue is the "skip this one" button. It's a tool for writing more precise, efficient, and intentional loops. Understanding continue is a hallmark of a developer who thin…  ( 12 min )

Há muito tempo eu tenho em mente a afirmação: “StringBuilder tem uma performance melhor que String”. https://lnkd.in/dzE95pjB Para o benchmark, criei um loop com 100.000 iterações fazendo concatenação de strings, com a mesma lógica tanto para String quanto para StringBuilder. 🔎 Resultado: A diferença é enorme, e o motivo é simples: String é imutável: cada concatenação cria um novo objeto, gerando muitos objetos temporários. Isso aumenta a atuação do Garbage Collector, afetando a performance. StringBuilder é mutável: todas as concatenações acontecem no mesmo objeto, evitando overhead desnecessário. Esse benchmark me deixou ainda mais atento sobre fazer escolhas conscientes quando a performance é crítica. Vale lembrar que existe também o StringBuffer, que é thread-safe e, por isso, naturalmente um pouco(sutil) mais lento que o StringBuilder. Mas em alguns benchmarks, o StringBuffer pode até ter performance tão boa quanto StringBuilder, mas deixo esse comparativo para um próximo post 😉 Usar System.currentTimeMillis() ou System.nanoTime() funciona para medições simples, mas quando se busca alta precisão, o JMH se destaca. Ele leva em conta fatores da JVM, como JIT, Garbage Collector e otimizações de compilação, oferecendo resultados confiáveis e reproduzíveis. Conhecer o JMH é importante, porque cedo ou tarde podemos precisar avaliar a performance de forma precisa e segura em nossos códigos Java.  ( 6 min )

Web services have become the backbone of modern applications. From mobile apps to enterprise solutions, almost every system needs to communicate and share data. Java, being one of the most powerful and widely used programming languages, provides strong support for building web services. This tutorial will guide you through the basics of Java web services, explain the different approaches, and provide code examples to help you get started. What are Web Services? A web service is a way for two applications to communicate over the internet using standard protocols like HTTP. It allows one application to send a request and another to send back a response, usually in a format like XML or JSON. In simple terms, a web service is like a messenger that enables different software applications (writt…  ( 8 min )

Mastering the JavaScript break Statement: Your Guide to Precise Loop Control Have you ever been in a situation where you’re looping through a list, you find exactly what you’re looking for, but the code just keeps going? It feels inefficient, like continuing to read every page of a book after you’ve already found the answer you needed. In programming, efficiency and precision are key. This is where the humble yet powerful JavaScript break statement comes into play. The break statement is a fundamental control flow tool that allows you to exit a loop or a switch statement prematurely. It’s the "emergency exit" or the "mission accomplished" signal for your loops. Understanding how and when to use break is crucial for writing clean, efficient, and performant JavaScript code. In this compreh…  ( 12 min )

1. Keep Components Small & Focused A React component should ideally do one thing well. If your file is 300+ lines, that’s a sign it needs to be broken down into smaller components. This improves readability and reusability. Instead of: const [val, setVal] = useState(false); Use: const [isOpen, setIsOpen] = useState(false); Your future self (and your teammates) will thank you. If you’re doing heavy computations in a component, wrap them in useMemo. const sortedData = useMemo(() => { return data.sort((a, b) => a.value - b.value); }, [data]); Not everything needs to live inside a useEffect. ❌ Bad: useEffect(() => { setFiltered(items.filter(i => i.active)); }, [items]); ✅ Better: const filtered = items.filter(i => i.active); Don’t wait until your app gets big. React DevTools can help spot wasted re-renders and performance bottlenecks even in early development. TypeScript catches bugs before runtime and makes your components more predictable. Even if you just start with props typing, it’s worth it. If you find yourself copy-pasting logic across components, extract it into a custom hook. function useToggle(initial = false) { const [state, setState] = useState(initial); const toggle = () => setState(prev => !prev); return [state, toggle]; }  ( 6 min )

Most beginners build a basic calculator in JavaScript when learning HTML, CSS, and JS.

Everyone’s talking about 2026 AI, but the real opportunity is how it will reshape jobs, products, and privacy faster than most teams expect. AI is moving from content to capability. The leap isn’t bigger models. It is new ways to build, simulate, and protect data. Code generation is maturing into full-stack builders with tests and data contracts. Synthetic datasets will unlock learning while keeping real user data safe. Multimodal AI will turn ideas into music, video, and 3D scenes on demand. Scientists will run complex simulations with AI copilots and get answers faster. Teams will prototype lifelike product videos and 3D spaces without massive crews. A mid-market fintech tested AI code generation on a reporting service. Time to ship fell from five weeks to three. Bugs per release dropped 28% after they added unit test prompts and evals. They kept PII safe by training on a synthetic ledger with privacy checks. Here is how to get ready in the next 90 days ↓ • Map your highest-friction workflows across code, data, and media. ↳ Pick one quick win per area and run a 30-day pilot. • Stand up a synthetic data sandbox with clear privacy tests and owners. • Build a simulation backlog with three must-answer questions per team. • Set guardrails early: evals, versioning, red-teaming, and an AI product owner. ⚡ Expect faster cycles, safer data, and sharper demos your buyers remember. ✓ Teams that do this see 25–40% cycle time gains within two quarters.

If you’ve ever spun your wheels on a side project, you’ll know the cycle: Start excited → stall → abandon → repeat. 😬 I wanted to break that loop, so I wrote a small handbook. It’s called The TenK 6 Handbook, and it’s 100% free to read online. 👉 Read the ebook here Instead of 300 pages of theory, this is a pocket-sized method built around 6 simple loops: List — capture ideas worth testing Pick — choose one without overthinking Ship — deliver something small, fast Ask — collect actual evidence (not vibes) Measure — see what’s working Share — tell the story, attract feedback Then… repeat. Each loop compounds into momentum rather than “yet another half-built repo.” Honestly? Because I got tired of my own side-project graveyard. I needed a system lean enough to actually use between coffee breaks, but structured enough to keep me accountable. So I boiled it down, tested it, and now you get the cheat-sheet version. Indie hackers tired of over-planning Developers who want more than “just build” Makers who like checklists but hate bureaucracy If you’re trying to get to your first $1 → $100 → $1k in revenue, this will help you stay on track. 🌐 Read the full ebook online 📥 PDF version: just click print icon on the ebook, the browser should generate one for you.

Building real-time features in FastAPI? Hit the wall trying to send messages from HTTP endpoints to WebSocket clients? Struggling with group messaging and scalability? Fast Channels brings Django Channels' battle-tested architecture to FastAPI and the entire ASGI ecosystem. FastAPI's native WebSocket support gets you started, but quickly becomes limiting: ❌ No group messaging - can't broadcast to multiple connections ❌ No cross-process communication - HTTP endpoints can't reach WebSocket clients ❌ Manual connection management - tracking users, rooms, cleanup ❌ No scalability - everything breaks with multiple server instances ❌ Testing nightmare - WebSocket unit tests are painful to write ✅ Group messaging - broadcast to chat rooms, user segments, notification groups ✅ Cross-process …  ( 7 min )

If you’ve ever launched a SaaS project, you know this pain: writing the product description is harder than building the actual product. You end up listing features nobody cares about. You try to sound clever but just sound like every other startup. Or worse—you freeze at a blank page and lose momentum. I wanted a repeatable way to write sharp, benefit-driven copy that converts. Something better than tweaking ChatGPT prompts endlessly. So I built the SaaS Product Description Generator. Input: Product name, target customer, and the problem it solves. Output: 5 short, benefit-driven descriptions (perfect for landing pages, hero sections, or social posts) + 1 longer description (great for directories, docs, and about pages). Consistency: Unlike ChatGPT “hit or miss” answers, this to…  ( 9 min )

1. 📝 Abstract Through comprehensive MySQL query performance experiments, this study systematically evaluates the effectiveness of SQL rewriting versus index optimization across different data scales and combination scenarios. Using a typical slow SQL query as our benchmark, we leveraged SQLFlash to generate optimized query rewrites and conducted comparative testing with various indexing strategies. 100x+ performance improvement from SQL rewriting alone (without any indexing changes) Millisecond-level response times when combining query rewriting with proper indexing Superior scalability compared to indexing-only approaches as data volumes increase The results demonstrate that structural SQL optimization provides both greater versatility and more sustainable performance during data growt…  ( 17 min )

Advent of Code 2024 Day 18 Part 1 Another variation of smallest possible answer A few of the last several puzzles required finding the smallest valid answer. One recent puzzle felt nearly identical to this one in that I had to explore every path within a maze from start to finish in order to identify the shortest path. I don't love these puzzle types because I haven't learned how to re-create a proper shortest-path algorithm, commonly referred to as Djikstra's algorithm or an A* algorithm, I believe. Instead, when I attempt them, I leverage the skills I have: recursion, novice memoization, and brute force Sadly, most of these puzzle variations show up after Day 12, where Part 2 is usually a test of identifying some pattern in the data to jump straight to the answer,…  ( 18 min )

One of the biggest myths about AI is that you need to be a developer to use it. Thanks to today’s tools, any entrepreneur, consultant, or educator can build AI-powered solutions — without writing a single line of code. Here’s a beginner-friendly guide to get started. 1️⃣ Start With a Real Problem Don’t begin with tools. Begin with a question: What repetitive task takes too much time? What customer pain point keeps coming up? Where does your business lose efficiency? Example: A consultant drowning in client reports doesn’t need Python scripts — they need AI to summarize and structure insights. 2️⃣ Use No-Code AI Tools There are dozens of platforms that let you build AI solutions with drag-and-drop interfaces: Zapier → automate workflows (e.g., auto-generate meeting summaries) Bubble → crea…  ( 9 min )

Have you ever worked on a data project that worked perfectly on your laptop… but broke as soon as you shared it with someone else? That’s where Docker shines. In this article, we’ll explore what Docker is, why it matters for data analysts and developers, and how to containerize a simple data project with one command. Docker is a platform built on open-source technology that lets you package your code, dependencies, and environment into a container — a lightweight, standalone unit that runs anywhere. Think of it like a magical box that holds everything your project needs to run, no matter where you open it. Reproducibility: Ensure your analysis runs the same on any machine. Isolation: Avoid dependency conflicts between projects. Portability: Easily share your code with coworkers or deploy …  ( 7 min )

In Ruby, it’s common to see the shorthand syntax using symbols as block arguments, such as &:to_s. Recently, more intuitive options like it and _1 have been introduced, which raises the question: should teams start unifying their style around them? This article explores the idea of intentionally avoiding the symbol block-pass syntax and shows a practical approach using RuboCop. Ruby has gone through several stages of block parameter evolution. # All of the following return ["1", "2", "3"] # The most primitive style [1, 2, 3].map { |i| i.to_s } # Since Ruby 1.9 [1, 2, 3].map(&:to_s) # Since Ruby 2.7 (Numbered Parameters) [1, 2, 3].map { _1.to_s } # Since Ruby 3.4 (it parameter) [1, 2, 3].map { it.to_s } The classic way requires explicitly naming a block parameter: [1, 2, 3].map { |i| i…  ( 7 min )

In this post, I'll explore what happens when you repeatedly apply partial manifests using Kubernetes Server-Side Apply (SSA). Specifically, I'll investigate through experiments what occurs when you omit fields that were previously managed by a field manager in subsequent applies. While developing controllers, I found myself wondering: "What happens to fields I don't include when applying partial manifests with SSA?" If only the submitted portions are merged as a diff, we could simplify our code by sending only the fields we want to manage. On the other hand, if we need to send all managed fields every time, we need to be conscious of this when coding, or we might accidentally create bugs that unintentionally delete fields. Developing controllers with incorrect assumptions could lead to bug…  ( 9 min )

Sometimes, what seems “simple” in front-end development can surprise you in the best way — a little challenge, a little learning. Today, I ran into a couple of tricky issues while building my React app with a sticky Navbar and shared Layout. Here’s what happened and what I learned. Layouts make life way easier I wanted my Navbar and Footer to show up on every page without having to copy them into every component. That’s where a Layout component really saved me. export default function Layout({ children }) { return ( {/* stays the same across pages */} {children} {/* page-specific content */} {/* stays the same across pages */} ); } Then, for each page route, I just wrapped it in the Layo…  ( 7 min )

The next step in privacy: A messenger that doesn't send data and doesn't keep your secrets. 🚀 💫 What if I told you that you could send messages without transmitting data AND without ever storing any secrets on your device?

In Chapter 1, we built a server that responded with "hello world" to every request. That's like having an API that returns the same response whether your frontend calls /api/users, /api/products, or /api/login. Not very useful! Today, we'll fix this by making our server route-aware - different paths will return different responses, just like a real API. From Chapter 1, we have a basic server that: ✅ Listens on port 3000 ✅ Responds to HTTP requests ❌ Returns the same response for every path When you write JavaScript like this: // Different endpoints, different data expected const users = await fetch('/api/users').then(r => r.json()) const products = await fetch('/api/products').then(r => r.json()) const profile = await fetch('/api/profile').then(r => r.json()) You expect different respon…  ( 9 min )

Ever made a fetch() call from JavaScript and wondered what's actually happening on the other end? Or used Gin/Echo/Fiber and typed r.GET("/users", handler) without thinking about what makes that route registration work? If you're a frontend engineer who's curious about what happens after your API request leaves the browser, or a backend developer who wants to understand what's beneath those convenient framework abstractions, this series is for you. Frontend Engineers: You know how to make HTTP requests, but what's actually running on that server responding to your POST /api/users calls? We'll build it from scratch.

"Effects specifically are still hard to understand and are the most common pain point we hear from developers." Quoted from the last blog post in the React documentation site. To this day, one of the most difficult concepts to wrap your head around as a React developer is using useEffect properly. Before React had hooks, components were written as classes that had a render function, a constructor to initialize state and several functions to manage the component's lifecycle, for example a componentDidMount function to run code when the component mounts to the DOM and a componentDidUpdate function to handle component state and prop updates. React 16.8 brought with it a list of hooks that created a new paradigm, instead of thinking about lifecycle hooks, developers were expected to think in …  ( 12 min )

Whether you’re a die-hard Java fan or a devoted PHP believer, chances are you’ve heard this phrase whispered in a forum thread or shouted over drinks late at night: “.NET? That thing can’t handle high concurrency.” This statement has stuck to .NET like a curse, haunting its reputation for years. But is it really true? Or is it just a misunderstanding born out of outdated technology? Like most myths, it had some truth—at least in the beginning. Early .NET Framework applications had two big drawbacks: Windows lock-in: The original .NET Framework was tied to Windows Server and IIS. You wanted .NET? You also needed the full Windows stack. That didn’t mesh well in a world dominated by Linux servers. Thread-per-request model: Early IIS favored a “one thread per request” approach. Simple, yes, b…  ( 8 min )

Ask any experienced developer and they will tell you: great code alone does not build great products. Behind every successful engineering effort is strong leadership that keeps the team focused, motivated, and ready to innovate. In fast-moving tech environments, leadership is more than project management. It is about creating an atmosphere where developers can experiment, learn, and deliver solutions that matter. Codebases evolve, frameworks change, and customer needs shift overnight. Without capable leadership, even the most talented team can lose direction. Effective leaders give developers the clarity they need to make smart decisions. They set a vision, remove roadblocks, and create a culture where creative problem-solving thrives. The best engineering leaders share certain qualities t…  ( 7 min )

Last week, I was profiling a Node.js service at Lingo.dev that was mysteriously slow. Chrome DevTools kept mentioning something called "Hidden Classes" in the performance panel. One accidental click on that term sent me down a rabbit hole that completely transformed how I write JavaScript.

When I was a junior dev, code reviews felt terrifying. Someone smarter than me would point out my mistakes, and I’d nervously push fixes. Over time, though, I realized code reviews weren’t about nitpicking—they were about growth, consistency, and shared ownership. Funny enough, when I stepped into a team lead role, I realized leadership works the same way. A single “Nice catch 👏” on a pull request can boost someone’s confidence way more than we think. The same goes for leadership—tiny moments of recognition go a long way. You don’t always need grand speeches; sometimes a quick “thanks” keeps morale high. Bad code reviews only focus on what’s wrong. Great ones explain why and guide toward a better solution. In leadership, feedback works the same. Criticism without context just frustrates people. But constructive feedback helps them grow. Even senior devs push buggy code sometimes. That doesn’t mean they’re bad—it means they’re human. Teams thrive when leaders normalize mistakes, treat them as learning opportunities, and help prevent them in the future. No PR is ever perfect. That’s why we merge, test, and improve continuously. Leadership is also iterative. You’ll never get it 100% right—but small, continuous improvements compound over time. In dev, we’ve built amazing tools for automation and CI/CD. But leadership often still runs on gut feeling. Recently, I stumbled across a resource about AI-driven mentoring for leaders that delivers real-time nudges—kind of like a “linting tool” for leadership habits. It really clicked with me, because it mirrors how we already use automation to make code better. Check it out here Code reviews don’t just make code better—they make devs better. And leadership, at its best, does the same for teams. So if you’re stepping into leadership as a developer, think about how you approach code reviews. Chances are, you already know more about leadership than you realize.  ( 6 min )

Introduction Modern applications rarely live in isolation. A single page load might involve calls to a payments API, a recommendation service, a geolocation provider, and your own backend. This web of dependencies makes apps powerful, but also fragile. What happens if one of these services slows down or starts failing? Without safeguards, your app may keep retrying, queuing up requests, or waiting on timeouts. The result: wasted resources, frustrated users, and sometimes cascading failures that spread from one misbehaving service into the rest of your system. This is where the circuit breaker pattern comes in. Inspired by electrical circuits, a software circuit breaker "opens" once failures reach a threshold. While the breaker is open, calls to the failing service are blocked immediately…  ( 18 min )

TL;DR: Many companies underestimate how something as simple as choosing a PDF form builder or a library can affect compliance. When multiple teams are involved, priorities diverge: Management focuses on cost, speed, and scalability; Legal focuses on regulatory obligations and liability; Design and Engineering prioritize user experience, functionality, and integration. Yet, it's easy to overlook how a seemingly minor detail such as where and how a third-party PDF filler or a PDF builder stores and processes user data can undermine all other priorities by introducing serious compliance violations. Because many PDF tool vendors operate as cloud-managed services, confidential data may pass through external servers or even jurisdictions where data and processing regulations may conflict with G…  ( 14 min )

Ever deployed a smart contract only to discover a critical bug the next day? You're not alone.

When we talk about Digital Signal Processing (DSP), we often start with signals. A discrete-time signal is at the heart of many technologies around us. From IoT devices that collect sensor readings, to AI systems that analyze audio and images, signals help us represent, process, and make sense of real-world data. I learned that understanding these signals gives us the foundation to build smarter and more efficient systems. In this post, I will walk through some basic discrete-time signals, show how I implemented them in MATLAB, and reflect on what we can learn. The unit impulse has value 1 at n=0 and 0 elsewhere. It is useful to test system response. MATLAB Output: The unit step signal stays 0 for negative values and 1 from n=0 onward. I use it to represent sudden switching in systems. MATLAB Output: The discrete ramp increases linearly with time. I see it often in modeling growth or incremental processes. MATLAB Output: An exponential signal grows or decays depending on the base. I learned that it is useful for modeling charging/discharging or population growth. MATLAB Output: MATLAB Output: The sinusoidal signal oscillates between positive and negative values. We see it everywhere in communication and control systems. MATLAB Output: By plotting and analyzing these signals, I now understand how discrete-time differs from continuous-time signals. A continuous signal flows smoothly, while a discrete signal has distinct sample points. This difference is critical in digital systems because computers and IoT devices only work with discrete values. We, as learners or developers, should remember that DSP is not just theory. It powers real-world applications like speech recognition, medical imaging, and smart sensors in AI systems. By practicing with MATLAB, I can visualize these signals and connect the math with practical uses. I believe that once you get comfortable with these basics, you will see DSP everywhere in your phone, car, or even in the devices at home. Explore the GitHub code: Discrete-time signals  ( 6 min )

Hello cyber enthusiasts and professionals, Today, I will be presenting the persistent threat of Fraudulent Resource Consumption (FRC) attacks and a proposed Gatekeeper solution below. Fraudulent Resource Consumption (FRC) attacks are a stealthy, yet prevalent threat to Cloud Service Providers with a goal to exploit unattended vulnerabilities and deplete CSP resources. These attacks aim to take advantage of the pay-per-use algorithm that most Cloud Service Providers such as Amazon Web Services and Microsoft Azure use. FRC attacks involve an attacker covertly gaining access to an unsuspecting Cloud user’s account and setting up automated fraudulent resource requests (botnet) in order to siphon network resources for personal gain or malicious intent. Damages to CSP’s are based on the utility …  ( 8 min )

Let's be real: spinning up a new component or a boilerplate MVP with an AI coding assistant like Cursor is the easy part. It feels like magic. The real challenge—the part that makes you want to pull your hair out—is getting it to fix a specific bug or make a small UI tweak without going completely off the rails. You type in, "The submit button is slightly misaligned on desktop." The AI cheerfully refactors your entire form, introduces three new bugs, and somehow changes the button color to neon green. Sound familiar? This gets 10x worse when bug reports come from non-technical folks. A ticket that just says "the login button is broken" is useless for a human dev, and it's even more useless for an AI that has no eyes, no browser, and no idea what the user was doing. It's the ultimate garbag…  ( 9 min )

Ever written a Python function that seems to do nothing? It’s a classic beginner bug, and it usually boils down to one subtle mistake: confusing print with return.

What print Really Does When you call print, Python pushes text to your console or terminal. That’s all. Under the hood, the function still returns None. def greet(): print("Hello, world!") result = greet() print(result) # None The greet() function lights up the screen with “Hello, world!” but leaves result empty-handed. print is communication with you, the human.

When you're deep in a debugging session that's going nowhere, or staring at legacy code that seems to defy logic, Amp has a specialized tool that can help: the oracle. By using this tool, you get access to OpenAI's o3, one of the most capable reasoning models available today. The Oracle grants Amp's main agent access to advanced reasoning capabilities when the standard approach is insufficient. While Amp typically runs on Claude Sonnet 4, which is fast, efficient, and perfect for most coding tasks, sometimes you need something with deeper analytical power. By using o3, the underlying model then trades speed and cost efficiency for reasoning depth. It's the model you want when you're dealing with complex system interactions, subtle bugs that span multiple files, or architectural decisions t…  ( 9 min )

Python loves a good plot twist. Few concepts deliver more surprise endings than mutability. At first, it seems like a vocabulary word you can skip past. But it shapes how your code behaves in sneaky ways: why one variable update spreads like wildfire, while another sits frozen in time. Let’s dig into what’s really going on. What “Mutable” Really Means A mutable object can be changed in place. Like clay, you can reshape it without throwing it out. A list is mutable. Append, extend, remove—it’s still the same list, just sculpted differently. A dictionary is mutable. Add or delete keys and the object lives on. Immutable objects are more like glass: they don’t bend. If you want something different, you have to create a whole new one. Strings are immutable. You can’t replace a single characte…  ( 8 min )

I just went through the process of publishing my MCP server (slimcontext-mcp-server) to the new official MCP Registry and wanted to share my experience with the dev community. The mcp-publisher CLI is straightforward once you get it working, but the experience felt rough around the edges. I had to retry publishing multiple times due to preview instability, and the whole thing felt like early-stage software (which, to be fair, it is). With all the private MCP catalogs that have emerged recently - Docker's MCP Catalog, various marketplaces, and other registries - I'm genuinely wondering if the official registry provides enough value right now. The private registries seem more mature, offer better discovery features, and have tighter integration with popular MCP clients. They're already battle-tested and working smoothly. For those who have published to both official and private registries: Are you seeing more adoption from the official registry? Is the "official" stamp actually driving more usage? Worth the extra effort, or better to focus on private catalogs for now? I wrote up the complete publishing walkthrough with all the technical details, but I'm more interested in hearing about real-world experiences. What's your take? Are you prioritizing the official registry or sticking with the private options that seem more polished right now?  ( 6 min )

Introduction Let’s recap the web’s evolution so far: Part 1: The backend ruled — it rendered pages, handled routing, and managed all logic. Part 2: AJAX and jQuery entered, letting us update parts of the page without reloads. Part 3: SPAs took over — shifting routing, validation, and rendering to the frontend. The JavaScript ecosystem exploded with complexity. Now in Part 4, we’re witnessing a new shift: A return to server-first thinking, progressive enhancement, and leaner web architecture — not by going backward, but by merging the best of both worlds. We’re building apps that are fast, interactive, and SEO-friendly — without overloading the browser. SPAs solved real pain points: smooth routing, rich interactivity, app-like behavior. But they came at a cost: Every h…  ( 9 min )

Introduction In the previous article, we saw how AJAX and jQuery transformed the web from a static, request-response model into something far more dynamic and interactive. But as applications became more complex, the patchwork of jQuery plugins, imperative DOM manipulation, and scattered logic began to collapse under its own weight. We needed more than snippets — we needed structure. And that’s when Single Page Applications (SPAs) emerged. A Single Page Application is a web app that: Loads a single HTML page initially Uses JavaScript to manage routing, rendering, and data updates Interacts with the server via APIs (typically JSON over HTTP) Avoids full-page reloads entirely In SPAs, the browser becomes the runtime — not just the display layer. Here’s how responsibilities changed …  ( 9 min )

Before SPAs, before frameworks — the web was simple, yet powerful. Let’s rewind. In this 4-part series, I’ll explore how the web has evolved — where it began, what changed, and where it's heading next. This first part takes us to the very beginning: how the web originally worked. The earliest versions of the web were built using a few core technologies: HTTP for communication HTML for structure CSS for styling JavaScript for light interactivity But the two most essential building blocks were: (anchor) tags for navigation elements for interaction That’s it. No client-side routing, no hydration, no JavaScript rendering. Everything was powered by server responses. Web apps in this era followed a simple cycle: All application data was stored in a database (like MySQL, PostgreSQL)…  ( 8 min )

Introduction In the first part of this series, we looked at the early web — a world of full-page reloads, where servers did most of the heavy lifting: from routing and rendering to data handling and UI feedback. But then something changed. A new technique emerged that allowed web pages to update without refreshing the entire page. This wasn't a new programming language. It was a new approach, and it reshaped how users interacted with the web. This is where AJAX enters the story. AJAX stands for Asynchronous JavaScript and XML. But don't let the name fool you — it's not limited to XML, and it's not a library or framework. It’s a combination of technologies: JavaScript (to make the request) XMLHttpRequest (the API, now replaced by **fetch**) The browser’s ability to update specific p…  ( 8 min )

Large refactoring projects are risky because they involve understanding complex dependencies, predicting ripple effects, and maintaining backwards compatibility. Of course, you can ask the Amp agent to refactor this to the best of its ability, but bringing in the Oracle to assist can make these large-scale refactors much more effective. The Oracle excels at analyzing complex and interconnected systems and planning refactoring approaches that minimize risk while maximizing the intended benefits. This guide demonstrates how to utilize Oracle to tackle a common use case, safely refactoring duplicate code patterns, while preserving existing functionality. For this example, let’s assume we have a task management API that supports notifications when tasks are completed. As the system has grown, …  ( 9 min )

Why you need a load balancer Imagine your website suddenly becomes popular. Hundreds or thousands of users are visiting at the same time. If all of them land on one server, that server will slow down, maybe even crash. The natural solution is to run more than one server — maybe two, three, or ten — and spread the traffic between them. The missing piece is a “traffic director” that decides who goes where. That’s what a load balancer is: it makes sure no single server carries all the weight. There are several ways to share traffic. Each approach works differently and comes with its own pros and cons: How it works: All traffic first goes through one main server — the reverse proxy. It accepts every request and forwards it to another backend server. This can be done at the transport layer …  ( 10 min )

What is SSAI? Server-Side Ad Insertion (SSAI) is a technology where ads are stitched directly into the video stream on the server before it reaches the viewer’s device.

In the fast-paced world of IT, development methodologies evolve rapidly, each promising to accelerate and simplify software creation. One of the latest paradigms gaining traction in 2025 is Vibe Coding, an AI-powered approach that is fundamentally reshaping how applications are built. Vibe coding is an AI-assisted software development technique where developers communicate with artificial intelligence through natural language prompts to generate functional code12. Rather than writing code line-by-line, programmers provide high-level instructions or goals — for example, "create a user login form" — and the AI automatically generates the underlying application code. This concept was popularized by AI researcher Andrej Karpathy in early 2025 and has since become a defining trend in AI develop…  ( 9 min )

Hey fellow developers! 👋 Just solved a classic frontend setup puzzle and thought I'd share in case anyone else is wrestling with the same issue. I was setting up Tailwind CSS in a React + Vite project and hit that frustrating wall where the styles just wouldn't apply. You know the feeling - you've followed the docs, everything looks right, but that beautiful blue bg-blue-500 just renders as plain white? Turns out I'd missed three crucial things: The content array in tailwind.config.js was empty (facepalm moment) - Tailwind needs to know which files to scan for class names! @tailwind directives need to be in your main CSS file (index.css, not App.css) Proper content paths: ["./index.html", "./src/*/.{js,ts,jsx,tsx}"] Complete PostCSS setup with tailwindcss and autoprefixer And of course, the classic "have you tried turning it off and on again?"

At the end of this article you will get the answers to the following questions: What is identity? What is authentication and authorization? What is access control? What are tokens? What is SSO? Now first let's start by understanding what identity is. Identity refers to the unique representation of a person or system within the digital ecosystem. For example: In real life your identity includes your name, fingerprint, photo ID, and in the digital world your identity includes your username, email, and user ID. Identity also includes some attributes which are known as identity attributes or claims. This is extra information about the user, for ex…  ( 8 min )

One of the most exciting parts of being a programmer is when you finally get to apply a concept you’ve learnt in a real-world scenario. In JavaScript, I learnt about higher order array methods like map() and filter(), but more importantly, how chaining them together might produce more sophisticated results, but it is one thing to know how these methods work, and another to solve an actual problem with them. That’s exactly what happened while I was building the multi-step form project from Frontend Mentor. I discovered a practical use case for chaining higher order array methods together, specifically map(). Here's a live demo of the project. Let's get into the nitty gritty In the 3rd step of the form, users are to select add-ons for their subscription plan. The application has two billing …  ( 8 min )

Understanding Raft: How Nodes Stay in Sync After Crashes In leader election systems, when one node goes down but the majority remain up, the leader can continue accepting and contributing new data. Example setup: node0 (leader) --- node1 (follower) --- node2 (follower) --- node3 (follower) Now imagine node3 crashes: node0 (leader) --- node1 (follower) --- node2 (follower) --- node3 (crashed) We see an error: err: node3 is down But that’s fine. As long as a majority of nodes (2 out of 3 followers) are still alive, the cluster continues contributing new data. Recovery scenario Let’s assume node3 comes back after five minutes. So what happens to node3 when it rejoins? Is it up to date? Obviously not, it’s missing those 3 contributions. The question is: how does node3 catch up with the rest of the cluster? The answer: Raft’s log replication Each contribution in Raft is stored in a log entry. i = log index t = term Before the crash After 3 new contributions Now the logs are inconsistent. That’s not what we want. How Raft fixes it When the leader sends the next log entry (say, i = 6), node3 pushes back: “Hey! My last index is 2, but you’re sending me index 6. Not acceptable!” The leader responds: “Ok, here’s the previous entry (i = 5).” But node3 complains again: “Wait… I only have index 2!” This back-and-forth continues until node3 receives a log entry with a matching previous index (i = 2). At that point, node3 accepts the next entries (i = 3, 4, 5, 6…) and catches up with the cluster. That’s Raft in action This process of syncing logs is how Raft ensures consistency across nodes, even when one crashes and comes back later. So in short: Raft uses logs to track contributions. When a node rejoins, the leader resends missing entries. The follower rejects mismatched logs until it finds the last known consistent entry. From there, it accepts new data and gets fully up to date. Hope you found this insightful! If so, leave a like and comment your thoughts below.  ( 7 min )

Everything you need to know about React Native and Android’s shift to 16KB memory pages — performance boosts, migration steps, and Play Store rules. If you ship React Native apps to Android, there’s a platform shift you can’t ignore: Android 15 introduces support for 16 KB memory page size. This brings measurable performance wins, but it also means some apps — especially those bundling native code (NDK/C/C++) — must be rebuilt or they won’t run on future 16 KB devices. The React Native team already added support in v0.77, so you’ve got a clear path. Let’s make sure you’re set up end-to-end.

Today's task is to create a hook to tell if it's the first render. The boilerplate code looks like this: export function useIsFirstRender(): boolean { // your code here } // if you want to try your code on the right panel // remember to export App() component like below // export function App() { // return your app { firstRender.current = false; }, []) return firstRender.current To know if we achieved our aim, we would display a message when the application renders. {firstRender: "First render" ? "Not first render"} We used a tenary operator which basically displays the first message if firstRender is true, or the second message if otherwise. The final code looks like this: import React, { useRef, useEffect} from "react"; export function useIsFirstRender(): boolean { // your code here const firstRender = useRef(true) useEffect(() => { firstRender.current = false; }, []) return firstRender.current } // if you want to try your code on the right panel // remember to export App() component like below export function App() { const isFirstRender = useIsFirstRender() return ( {isFirstRender ?

I recently did a video tutorial on using jobs and queues in PayloadCMS and the solution I provide will not work in a Vercel deployment, runs locally and will probably also run on Railway because those are actual servers. This blog post explains why and walks you through how to update the project to run on Vercel. Get the source code here The "Why": Serverless vs. Long-Running Processes The code in the video uses Payload's built-in jobs queue, which relies on a long-running Node.js server process. The autoRun: true setting starts a persistent "clock" (setInterval) inside your server that checks every minute if a job needs to run. With Vercel, however, since it is a serverless platform, your code doesn't run on a server that is "always on." Instead, it's packaged into serverle…  ( 10 min )

Classification is the art of drawing boundaries. You take messy, high-dimensional data and force it into neat categories. In the wild, this could be spam vs. not-spam, cat vs. dog, tumor vs. healthy tissue. In textbooks, it’s often MNIST, the 70,000-image dataset of handwritten digits that’s become the “Hello World” of machine learning. MNIST looks simple, but it hides the essence of classification: Inputs: images, each a 28×28 grid of pixels → vectors in R784\mathbb{R}^{784}R784 . Outputs: 10 possible digits (0–9). Goal: learn a function f:R784→0,1,…,9f: \mathbb{R}^{784} \to {0,1,\dots,9}f:R784→0,1,…,9 . That’s it.

In today's fast-paced business environment, organizations are constantly seeking ways to improve operational efficiency, reduce costs, and enhance productivity. Workflow automation has emerged as a transformative solution that leverages technology to streamline repetitive tasks and complex business processes, enabling teams to focus on higher-value activities that drive innovation and growth. Workflow automation is the process of using technology to automate manual, repetitive tasks and business processes by creating predefined rules, triggers, and actions. Instead of relying on human intervention for routine operations, automated workflows execute tasks based on specific conditions, routing work between people and systems seamlessly[18][20][32]. At its core, workflow automation combines s…  ( 11 min )

Today I explored Rc, the Reference Counted Smart Pointer in Rust. This is where ownership gets interesting—sometimes a value might need multiple owners, and Rc provides exactly that functionality. Normally, ownership in Rust is strict: only one owner exists for any given value. But in real-world cases, multiple parts of a program may need to share access. For example, in graph structures, multiple edges may point to the same node. That node shouldn’t be deallocated until all edges stop pointing to it. Rc keeps track of the number of references to a value. Once all references are gone, the value is safely cleaned up. 👉 Think of Rc like a TV in a family room: everyone can watch while they’re in the room, and only when the last person leaves is the TV turned off. ⚠️ Rc works only in singl…  ( 7 min )

Quick Summary This article explores how to handle gaps in data and make sure your charts don’t quietly mislead. A must-read if you care about honest visual storytelling. Consider, the case of a line chart: where discrete data points are plotted along X and Y axes and connected to form a continuous line. Though the underlying grid may technically support an infinite number of coordinates, the chart typically displays only a finite set of values. The regularity of intervals between these points—along with axis labels and contextual annotations—enables the viewer to infer patterns and anticipate trends. On occasion, there exists an unexpected discontinuity—a gap in the data. When such an absence occurs without explanation, it can render the chart misleading, implying continuity where none …  ( 7 min )

The rise of AI-powered apps has introduced a new class of security vulnerabilities that traditional security frameworks weren't designed to handle. Prompt injection attacks, jailbreaking attempts, and role confusion exploits can compromise AI systems in ways that bypass conventional input validation. PromptChainmail introduces a novel security architecture based on two core concepts: export type ChainmailRivet = ( context: ChainmailContext, next: () => Promise ) => Promise; Rivets are sequential middleware functions that process input through a pipeline. Each rivet can inspect, modify, or block content before passing it to the next rivet in the chain.

I recently set up a multi-AZ AWS VPC environment to host a website, and this process turned into a real-world lesson in cloud networking. Below is a breakdown of the entire journey from subnets and gateways to bastion access and load balancers. 1. Subnets and Internet Gateway I provisioned a VPC in us-west-1 with CIDR 10.0.0.0/16. Inside it, I created four subnets across two Availability Zones for fault tolerance: 10.0.1.0/24 → Public subnet in AZ1 (us-west-1a) 10.0.2.0/24 → Public subnet in AZ2 (us-west-1c) 10.0.3.0/24 → Private subnet in AZ1 10.0.4.0/24 → Private subnet in AZ2 By default, subnets are private (no route to the internet). To make the public subnets truly public: Attached an Internet Gateway (IGW) to the VPC Created a public route table: Destination Ta…  ( 10 min )

In the previous post, we tunneled a local MCP server with ngrok to expose internal services externally (for testing and integration, demo access, branch office access and other scenarios). Now let’s do the same for a Kubernetes-hosted workload managed by ToolHive. This is very much a production scenario in which exposed MCP servers are also exposed via Kubernetes clusters; but with ToolHive and ngrok, we can keep the approach simple. Once you’ve got ToolHive and ngrok up-and-running, just follow the steps below: Follow the ToolHive Kubernetes Operator quickstart to install the operator and deploy an MCP server in your cluster (I’m using the fetch server here).

Too often we see development teams struggle to finish a project. Here is a nice open-source framework I wrote to help with your upcoming microservices (or legacy!) project: the pipeline framework. https://github.com/mbarcia/CSV-Payments-PoC/tree/main/pipeline-framework Welcome to the Pipeline Framework - a robust, scalable, and maintainable solution for processing data through a series of steps with built-in benefits for high-throughput, distributed systems. Step-based Processing: Each business logic operation is encapsulated in a step that implements a specific interface. Reactive Programming: Steps use Mutiny reactive streams for non-blocking I/O operations. Type Safety: Steps are strongly typed with clear input and output types that chain together. Configuration Management: Steps can be configured globally or individually for retry logic, concurrency, and more. Observability: Built-in metrics, tracing, and logging for monitoring and debugging. It doesn't ask for much, only that you translate the business case into a "pipeline" model with each step having a defined input/output. You only write the business logic for each step and the framework will do all the Kubernetes heavy lifting for you (messaging, auto-persist, error handling, etc.) I'm in the process of making it an independent set of JARs on Maven central. At the moment it is included in the "CSV Payments Processing" system which is its "reference implementation". Reach out to me in the comments if you would like to know more. Cheers.  ( 6 min )

The next evolution of LLM-generated code or code modification isn’t another fine-tuned model, nor is it a singular new tool or a tool chain. The next evolution of LLM code generation is going to be much deeper than you expect.

Cursor, Windsurf, Codex, and cli tools like Gemini/Claude/Warp all do the same thing with a different coat of paint. They all optimize context stuffing, and not in a cost-effective manner.

Even if you’re hustling to grow fast, skipping compliance now can come back to bite you when you start chasing those bigger deals. When you get SOC 2 compliant, you’re showing clients and investors you actually care about security. That can help you close deals faster and just feel a bit more confident as you grow.

On Day 4 of my Python challenge,I learned about type casting. Type casting means converting one data type into another for example, changing a number into text, or text into a number (if possible).This is super useful when working with user input or combining different kinds of values. Here’s the code I wrote today: # Integer to float num_int = 10 num_float = float(num_int) # Float to integer decimal_num = 5.9 whole_num = int(decimal_num) # Number to string age = 22 age_str = str(age) # String to integer num_str = "100" num_from_str = int(num_str) print("Integer to float:", num_float) print("Float to integer:", whole_num) print("Number to string:", age_str) print("String to integer:", num_from_str) What happened when I ran it? Notice how the data type changes when we cast it: int → float adds a decimal (10 → 10.0) float → int drops the decimal part (5.9 → 5) int → str turns numbers into text (22 → "22") str → int only works if the string is a number ("100" → 100) GitHub update: git add 'day4(type_casting).py' git commit -m "type casting..." git push Challenge for you: Try converting "3.14" into a float. Then convert it into an integer.What result do you get? Your turn: Have you ever had a situation where you needed to convert data types (maybe while coding, or even thinking about real life like changing “22” to 22 😉)?Share your examples in the comments!  ( 6 min )

The Silent Data Loss Problem Every Multi-User App Faces Multi-user applications have a dangerous default behavior that many developers don't realize until it's too late. When multiple users modify the same data simultaneously, the last person to save wins, and everyone else's changes disappear without a trace. Silent data loss. No exceptions thrown, no error messages, no warnings - just data quietly vanishing. The good news? EF Core has a built-in solution that requires just one attribute. In multi-user applications, the default behavior is deceptively dangerous.

Timers are everywhere — from GUIs to embedded systems — but not all C++ frameworks handle them the same way.

Areg delivers per-thread timers that are: ✅ Accurate (not bound to GUI refresh rates) ✅ Thread-aware (fires in the owning thread) ✅ Flexible (one-shot, periodic, cyclic) 🔎 Quick Comparison Feature Areg ⚡ Qt QTimer 🎨 POCO Timer ⚙️ Thread-Aware ✅ Target thread ⚠️ GUI/event loop needed ⚠️ Callback thread unclear Single-Shot/Periodic ✅ Supported ✅ Supported ⚠️ Manual setup required Cyclic/Repeated ✅ Until st…  ( 7 min )

If you’re a Shopify dev or agency, you know how often clients ask for wishlist functionality. It’s a feature that boosts engagement, gives shoppers more flexibility, and can increase sales — but building it in a way that keeps things performant and customizable often feels like walking a tightrope. That’s exactly why we built the new web component for Wishlist Power. Here’s what it does, how it works, and why agencies are going to love it. Drop-in integration — place the component in product pages, collection's product cards or even the home page without writing a line of JavaScript. Full styling control — you manage the HTML and CSS, so it looks exactly like the rest of the store. Variant awareness — track variant IDs or let the component detect variant changes automatically.

In the ever-evolving landscape of software development, quality assurance is the foundation of reliable products. Among the many testing approaches available, white box testing stands out as one of the most thorough and transparent methods. Unlike black box testing, which focuses only on external behaviors and outcomes, white box testing opens up the software like a glass container—allowing testers and developers to peer into its inner logic, execution paths, and architecture. Why is this important? Because modern applications are no longer simple. They’re complex systems running on microservices, integrating with external APIs, handling sensitive user data, and needing to meet both performance and security demands. Testing only at the surface level isn’t enough. To truly ensure trust, per…  ( 10 min )

When you hear Lazarus Group, the image is clear: North Korea’s state-backed hackers, orchestrating precision cyber heists, draining banks, and rattling global security. They are the archetype of cybercrime’s elite, faceless, feared, and calculated. But while Lazarus operated in the shadows, another empire rose in broad daylight. On Telegram, far from the hidden recesses of the dark web, Haowang Guarantee, once known as Huione Guarantee, became the beating heart of a global scam economy. It wasn’t just a crew pulling off jobs; It was the marketplace itself. A hub where pig-butchering scams wiped out retirements, and money-laundering pipelines moved billions in dirty crypto with ease. By the time Telegram slammed the door shut in May 2025, Haowang had already facilitated over $27 billion …  ( 10 min )

TLDR Treat prompts like code. Version them, test every change, ship through environments, and trace what’s happening in prod. Use a Git-style workflow for prompts, semantic diffs, templates, environment-aware rollouts, and CI/CD with automated and human evals. Layer in observability and a gateway for rollback, routing, and cost control. If you’re building with LLMs, you already know: prompts are code, but they drift like data. One “tiny” change to a prompt or variable can tank accuracy, spike latency, or blow up costs. If you don’t have version control for prompt management, you’ll get regressions, brittle prompts, and bugs you can’t reproduce. Here’s the playbook: Version prompts with structure. Run evals (automated and human) before you ship. Deploy through environments, not straig…  ( 8 min )

TL;DR Modern browsers are unreliable for large file downloads from dynamic or expiring links because they can't properly resume failures. This note provides two Windows batch scripts (for wget and aria2) that solve this problem. Using session information (HTTP headers and cookies) extracted from your browser's dev tools, these scripts can robustly resume downloads, even if the link needs to be refreshed. Modern web browsers often fail to robustly download large files (e.g., OS images) over unreliable or slow connections. There are two primary reasons for this: Limited Resume Capabilities: Standard browser downloaders often cannot properly resume a failed download, deleting the partial file and forcing a restart. Dynamic & Expiring Links: Many services no longer provide direct download …  ( 9 min )

For clean installs of macOS or installs on multiple computers with only one download, creating a bootable macOS installer on a USB drive is the way to go. Up to Sequoia, Apple released standalone installers for the major releases of macOS on the App Store. For Tahoe, however, there's no such thing and probably never will. The installer is available on third-party download sites, but it is an incredibly bad idea to use any of them, no matter how trustworthy it may look. Just don't do it! Also, there's no reason to take such unnecessary risks – with a little help of the Terminal. You'll need a big enough USB drive. Use the Disk Utility to erase it to HFS+ format and the default name /Volumes/Untitled. Then launch the Terminal and: # Find the installer for the version of macOS you wish to install softwareupdate --list-full-installers # Download the installer app softwareupdate --fetch-full-installer --full-installer-version {VERSION} # Create a bootable installer on the USB drive: sudo "/Applications/Install macOS {MACOS_NAME}.app/Contents/Resources/createinstallmedia" --volume /Volumes/Untitled That's it, easy as 123 and free as in free beer! I won't go into much detail here, but the basic steps are as follows: Create a Time Machine backup. Create a second, full backup using SuperDuper, Carbon Copy Cloner or a similar tool. Make sure you have successfully completed the steps 1 and 2. Attach the USB drive containing the installer. Shut down your Mac, then restart it into boot options: On an Apple Silicon Mac, push and hold the power button. On an Intel Mac, push the power button, then hold the option key (⌥). Use the Disk Utility to erase the startup disk to APFS. Use the macOS installer on the USB drive to clean install macOS. Migrate your data from one of the backups onto the fresh macOS.

The Basics of File Handling in Python Python provides powerful tools for working with files, allowing you to read and write data effortlessly. Let's dive into the fundamentals of file handling in Python. Opening and Closing Files Before you can read or write to a file, you need to open it using the open() function. Remember to close the file using close() once you're done to free up system resources. file = open('example.txt', 'r') Reading from Files You can read the contents of a file using methods like read(), readline(), or readlines(). Experiment with these methods to extract data efficiently. with open('data.txt', 'r') as file: Writing to Files To write to a file, open it in write or append mode and use methods like write() or writelines() to add content. Don't forget to handle exceptions using try-except blocks. try: Manipulating File Pointers You can move the file pointer using methods like seek() to navigate within a file. This allows you to read or write at specific positions. with open('data.txt', 'r') as file: Advanced File Handling Techniques Working with Binary Files Python supports reading and writing binary files using modes like 'rb' and 'wb'. This is useful for handling non-textual data like images or executables. Handling Exceptions When working with files, it's essential to anticipate and handle exceptions like FileNotFoundError or PermissionError. Use try-except blocks to gracefully manage errors. Using Context Managers Context managers, implemented with the with statement, ensure that files are properly closed after use, even if an exception occurs. This simplifies file handling and improves code readability. Conclusion Python's file handling capabilities empower developers to work with external data seamlessly. By mastering file operations, you can efficiently manage file I/O tasks and build robust applications. Experiment with different file handling techniques to unleash the full potential of Python!  ( 7 min )

I recently worked on a project that let me explore some exciting areas like: Building Telegram bots Using WhatsApp APIs Playing with asynchronous programming Developing and consuming APIs The result? 👉 WATele-Bridge – a simple, self-hosted bridge between Telegram and WhatsApp. The project has two main parts: Telegram Bot (Python, Telethon) Listens for new messages from a user-specified chat, group, or channel. Whenever a new message arrives, it triggers an event handler. That event makes an HTTP request to an API endpoint. WhatsApp API (Node.js, '@whiskeysockets/Baileys') Exposes a send-message endpoint. Receives the incoming request from the Telegram bot. Forwards the message directly to WhatsApp. This essentially creates a Telegram → WhatsApp relay. I wanted to: Learn Telethon for Telegram bot development. Explore Baileys (a popular WhatsApp Web API library). Understand how to design async message handling. Practice building and integrating a small microservice API. It’s a great project if you’re curious about combining different chat platforms or experimenting with real-time communication apps. You can self-host the project with the instructions in the repo: This is still a work in progress, and contributions are very welcome. Some possible improvements: Adding support for two-way sync (WhatsApp → Telegram) Deployment scripts (Docker, PM2) Better logging and error handling Adding the ability to listen from multiple Telegram chats This was a fun experiment that combined multiple APIs and asynchronous programming. If you’ve ever wanted to link two messaging platforms, this project might give you a head start.  ( 6 min )

Introduction Schema is a structural of a database its tables columns and relationship. A star schema is a widely used data modeling technique in data warehousing that organizes data into a central fact table surrounded by multiple dimension tables We can use schema to structure most of our database to know what to place in our databases.  ( 6 min )

When your system grows to millions of users, even the simplest operations—like checking if a phone number or email already exists—can become costly. Yes, you can add database indexes, but every lookup still eats up I/O and CPU cycles. Under heavy signup traffic, this can quickly overwhelm your database. This is where Bloom Filters come to the rescue. 🌸 A Bloom Filter is a probabilistic data structure used for set membership checks. It allows us to ask: 👉 “Does this value possibly exist?” It can say: ❌ Definitely Not → Safe to skip DB. ✅ Might Exist → Confirm with DB. This tiny compromise (allowing false positives, but never false negatives) gives us O(1) lookups with very little memory usage. At its core, a Bloom filter is just: A Bit Array (size m) → starts with all 0’s. k Hash Function…  ( 9 min )

Connecting an ultrasonic sensor like the common HC-SR04 to an Arduino Uno (or any similar board) is a fundamental project. The process for an "Arduino Uno32" is identical to a standard Arduino Uno, as the pin functionality and voltage levels are the same. Here is a clear, step-by-step guide. 1. How an Ultrasonic Sensor (HC-SR04) Works VCC: Power (5V) Trig: Trigger Input Pin Echo: Echo Output Pin GND: Ground It operates by: You send a short 10µs HIGH pulse to the Trig pin. The sensor sends out an ultrasonic burst (8 pulses of 40kHz). The sensor then sets the Echo pin HIGH. It keeps the Echo pin HIGH until the burst reflects back and is detected. You measure the duration the Echo pin was HIGH. The longer the duration, the farther the object. You then calculate distance using the speed of so…  ( 8 min )

Cleaning Messy Data: Why It’s 80% of the Job let us Talk About it 🧹📊 When people think of data science, they imagine machine learning models, fancy dashboards, and mind-blowing insights. But the real tea? Most of the time is spent cleaning messy, chaotic data before you even touch the fun stuff. Garbage in = garbage out. Models can’t save bad data. Clean data = faster insights. Missing values that mysteriously disappear 👻 Duplicates that never seem to end Columns with 20 different spellings of the same thing (looking at you, "Nairobi"/"nairobii"/"Nairobiii") see!! Python + Pandas: the classic combo Excel: don’t sleep on it! SQL: when datasets get big and messy Takeaway Data cleaning isn’t glamorous, but it’s the backbone of every project. Think of it like doing dishes before cooking you can’t ignore it if you want a great meal. 💬 What’s the messiest dataset you’ve ever had to clean?  ( 6 min )

Had a background job in Kubernetes. Super simple - check for pending work every 5 minutes: setInterval(() => { checkPendingJobs(); // Send emails, process data, cleanup tasks }, 5 * 60 * 1000); Deployed to 3 pods for "high availability." Big mistake. Monday morning: Users getting duplicate emails, database CPU spiking. Checking logs: Pod-A: Processing job #123 - sending welcome email Pod-B: Processing job #123 - sending welcome email Pod-C: Processing job #123 - sending welcome email All 3 pods wake up at the exact same time, query the database, find the same pending jobs, and process them in parallel. Classic race condition. Tried database locks. Tried Redis locks. Tried leader election. All complex, all brittle. Then realized something obvious: Why am I trying to coordinate 3 workers when I only need 1 job to run? Deleted the setInterval. Made it an HTTP endpoint: app.post('/jobs/process', async (req, res) => { await checkPendingJobs(); res.json({status: 'done'}); }); Added external scheduler (GCP Cloud Scheduler): gcloud scheduler jobs create http my-job \ --schedule="*/5 * * * *" \ --uri="https://myapp.com/jobs/process" That's it. Scheduler hits the endpoint, load balancer picks one pod, job runs once. No race conditions possible - only one request Way less code - no coordination logic Better reliability - managed scheduler vs app timers Easier debugging - clear request logs Works everywhere - AWS EventBridge, cron, whatever Stop asking "How do I coordinate multiple instances?" Start asking "Do I need multiple instances doing this?" Most background jobs are perfect for external triggers: File processing → storage events Cache warming → deployment hooks Cleanup tasks → schedulers Health checks → external monitoring Been running this for months. Zero duplicate jobs. Zero 2 AM alerts. Sometimes the best distributed systems solution is... not distributing the work. Similar war stories? Drop them below.  ( 7 min )

The Rust data ecosystem has reached another significant milestone with Elusion DataFrame Library surpassing 50,000 downloads on crates.io.

Introduction A database schema defines how data is organized within a relational database; this is inclusive of logical constraints such as, table names, fields, data types. A star schema is a data modeling technique for data warehouses that features a central fact table surrounded by several denormalized dimension tables , resembling a star. It is a multi-dimensional data model that is an extension of a star schema, where dimension tables are broken down into subdimensions. In summary, star schemas offer simplicity and fast query performance, while snowflake schemas provide a normalized structure that saves space but adds complexity. The choice depends on your specific data needs.  ( 6 min )

I’ve just completed the coding and initial training of a Convolutional Neural Network (CNN) on my dataset. The model is designed for image classification and follows a standard architecture: several convolutional layers extract features from the images, followed by pooling layers to reduce dimensionality. The extracted features are then flattened and passed through fully connected layers, ending with a softmax output for classification. The code handles data loading, preprocessing, model definition, training, and evaluation, and I’m now able to make predictions on new images with the trained model. The CNN gives a solid baseline, but for more complex datasets or higher accuracy, more advanced architectures can be beneficial. My next step will be working with EfficientNet-B2, a state-of-the-art CNN model pre-trained on ImageNet. EfficientNet often outperforms standard CNNs because it scales depth, width, and resolution more efficiently, which usually results in better accuracy with fewer parameters. I’m excited to see how it improves the model’s performance on my dataset. Stay tuned for updates on the EfficientNet training and results!  ( 6 min )

Exception handling is essential for building robust, user-friendly APIs.

Another week, another update! I could kind of improvise on how to position a big object in the middle of the screen. For example if the window width is 1280 and the board width is 150 I'd take half of 1280 which is 640 and subtract 150 from it and set it as the X coordinates of the board because the top left side of the object is the starting point I also learned how to handle bounces in a somewhat easy way which I'll talk about in a later section And I faced quite difficult ones! Firstly it's not really a problem but I would always forget to call the functions after making them. Then when I'd run the code I'd be surprised that why something isn't working Another one, which I mentioned earlier was the collision of the ball with the player board and the window. This one took the most brain work out of me and took a while for me to come up with a solution that would meet my standards. Good question, friend. Now I wanna implement more things to it that I have in mind such as: PLAYER 2 and it's controls, probably a net and a "field" between the 2 players, and in general a touch up to the whole game to make it look more like a 2 player tennis game. Until next week, stay safe, and take care of yourselves!  ( 6 min )

Back when I was preparing for my first Big Tech interview, I prepped the way most engineers do: reviewing concepts, solving hundreds of LeetCode problems, and watching every System Design video I could find. After months of grinding, I thought I was ready. For a final check, I set up a mock interview with a friend who had just joined Microsoft. It went well enough. I solved the algorithm, explained my approach, and wrapped up on time. But then I asked them a simple question: “Did I justify my decisions well enough?” They gave me a generic answer and moved on. The feedback wasn’t wrong, but it wasn’t useful either. I walked away with more questions than answers. That’s when I realized the gap in my prep: I could solve problems, but I had no way to measure how I came across in the conversati…  ( 11 min )

If statements are one of the most common constructs in programming — but they can get messy fast. Nested ifs, long logical chains, and hard-to-read conditions make code brittle and harder to maintain. Luckily, binary algebra (Boolean algebra) provides a powerful set of tools to simplify these conditions. Let’s break this down in a beginner-friendly way. Binary (or Boolean) algebra deals with values that can be either true or false. The three basic operations are: AND ( ∧ ) – true only if both sides are true. OR ( ∨ ) – true if at least one side is true. NOT ( ¬ ) – inverts the value (true becomes false, false becomes true). In most programming languages, these are written as: && for AND || for OR ! for NOT Binary/Boolean Algebra have set of rules to implement : Consider this code: if ((is…  ( 7 min )

If you’re new to Kafka, you’ve probably asked yourself: “When a producer sends a record, what does Kafka actually store on disk? Is it JSON? Avro? Hex? Bytes??” I recently went down this rabbit hole myself — so here’s a breakdown of what really happens behind the scenes. Bytes Let’s clear the air first: Kafka doesn’t know or care about JSON, Avro, Protobuf, POJOs, or unicorns 🦄. It only deals in byte arrays (byte[]). Producer sends: byte[] key, byte[] value Broker writes to log: byte[] Consumer reads: byte[] Everything else (JSON, Avro, Protobuf, String) is just a serialization format layered on top. Two words that get thrown around a lot: Serialization = turning an in-memory object (like a Java POJO) into a storable/transmittable format. Encoding = mapping characters into bytes…  ( 7 min )

Hallo world! Pada postingan ini kita akan membahas gimana cara membedakan partisi LVM atau bukan. Pertama kita bisa menggunakan lsblk tools. Jalankan perintah berikut lsblk -o NAME,FSTYPE,SIZE,MOUNTPOINT Jika outputnya ada LVM2_member, berarti partisi itu dipakai LVM. tapi kalau langsung ext4, xfs, btrfs, berarti bukan LVM. Atau berikutnya bisa menggunakan pvdisplay, jalankan perintah berikut pvdisplay Jika ada output (nama PV, VG, LV), berarti ada LVM, tapi jika kosong maka sistem tidak pakai LVM. Oke selanjutnya kita akan bahas gimana cara resizenya. Kita samakan asumsi, disini saya ingin memperbesar partisi root dari 300GB ke 600GB. Sebelumnya saya sudah memperbesar size disknya via proxmox management web ui. Jadi seharusnya jika di cek dengan fdisk akan ada perubahan size. Meskipun sizenya telah berubah tapi ini belum bisa di pakai. Karena jika di cek dengan df -h size / masih sama belum ada penambahan kapasitas. Ok, dari studi kasus di atas kita akan coba memperbesar kapasitasnya dan meminimalisir downtime. langsung saja ke caranya Pastikan partisi root, cek dengan: lsblk Lihat mana yang dipakai untuk / (root), pada kasus ini root berada di /dev/sda1. Lanjut resize partisi /dev/sda1, gunakan tool growpart, jika belum ada toolsnya install dulu: apt install cloud-guest-utils -y lalu jalankan growpart /dev/sda 1 Itu akan memperbesar partisi /dev/sda1 supaya sesuai dengan ukuran disk baru (600GB) Setelah resize partisi baru kita resize filesystem, jika filesystem kita ext4, maka jalankan resize2fs /dev/sda1 Tapi jika filesystem kita xfs, maka jalankan: xfs_growfs / Setelah sudah, selanjutnya cek hasil df -h Sekarang harusnya kapasitas root berubah jadi 600GB. Ringkasnya: Proxmox GUI berhasil resize disk (600GB sudah terbaca). Ubuntu VM partisi root masih 300GB, harus di-extend manual dengan growpart + resize2fs. Semoga bermanfaat dan selamat mencoba.  ( 7 min )

A browser builds a webpage step by step: Reads the HTML file top to bottom. It converts the text into tokens, then into the DOM tree. If the browser encounters a tag without async or defer: It pauses HTML parsing immediately. Downloads the JavaScript file (if external). Executes that JavaScript. Only after execution finishes does it resume building the DOM. Because JavaScript can modify the DOM or CSSOM while the page is loading. For example: Hello Hello . Hits → stops everything. Downloads + runs big-script.js. 4 After execution → continues parsing . appears later, delaying rendering. Case 2: Script with defer Hello tag until that script is fully executed.  ( 6 min )

Imagine you're sending an important letter to a friend through the mail. Before sealing the envelope, you take a photo of the letter. When your friend receives it, they take another photo and send it back to you. If the two photos match, you know the letter arrived untampered and intact. If they don't, something went wrong during transit—perhaps the letter was altered or damaged. In the digital world, checksums serve a similar purpose. Just as photos verify the integrity of a physical letter, checksums answer the question: Has this data been altered unintentionally or maliciously since it was created, stored, or transmitted? In this article, we'll dive into what checksums are, how they work, their types, and their real-world applications. What is a Checksum? A checksum is a unique digital …  ( 7 min )

A few weeks ago, I was deep in coding flow when I caught myself doing something annoying for the hundredth time: open browser → search DevPromptly → copy a prompt → paste into VS Code → tweak → finally continue coding. That’s when I thought: “Why am I breaking my flow just to grab prompts? What if I could bring them straight into VS Code?” That was the spark. At first, I thought building a VS Code plugin would be simple. “Just show a list of prompts, add a button, done.” The moment I opened the docs, reality hit. Extensions have their own lifecycle, APIs, constraints, and the UX expectations are high. If it feels clunky, devs won’t use it. But I was stubborn. I wanted something that felt smooth — browse, search, and insert prompts in a couple of clicks, without leaving the editor. This was…  ( 8 min )

The web we know today is built around 2D documents. HTML, CSS, and JavaScript together create interfaces inside a flat, rectangular viewport. But what happens if we bring the entire web into 3D space? That’s the question the JSAR Spatial Browser Engine is tackling. Instead of patching existing 2D browsers, JSAR reimagines the browser from the ground up as a spatial-first engine. 👉 Full article here: Understanding the Spatial Web Browser Engine | YODAOS JSAR A spatial browser doesn’t just render content on a 2D plane. Instead, it loads HTML, CSS, JS, WebGL/WebXR, and media into a 3D coordinate system. DOM elements (text, images, forms, canvas, video, etc.) exist as 3D objects with position, rotation, scale, and depth. Users interact through spatial inputs like gaze, gestures, and controll…  ( 7 min )

Debugging GPU code can be more complex than debugging CPU code due to several factors inherent to the massively parallel nature of GPU computations and the distinct architecture of GPUs. Here are some of the biggest challenges and strategies to overcome them: Massive Parallelism: GPUs execute thousands to tens of thousands of threads concurrently, making it harder to understand the state of the program at any given time. Traditional debugging techniques like stepping through code or examining variable values become impractical due to the sheer number of threads. Asynchronous Execution: Many GPU operations, such as kernel launches and memory transfers, are asynchronous. This asynchrony can make it difficult to understand the order of events and the state of the program. Limited…  ( 8 min )

1️⃣ What is SSA? SSA is a way of representing code where: Each variable is assigned exactly once. If a variable is reassigned → the compiler creates a new “version” of that variable (x1, x2, x3 …). When there are multiple control-flow branches (if/else), the compiler uses a φ-function to “merge” values back together. 🔎 Note: SSA is not a new kind of IR on its own, but rather a specialized form of IR. Compilers convert their Intermediate Representation (IR) into SSA form to make analysis and optimization easier. Original code: x = 1; x = x + 2; y = x * 3; After converting to SSA: x1 = 1; x2 = x1 + 2; y1 = x2 * 3; Original code: if (cond) { x = 1; } else { x = 2; } y = x + 3; After converting to SSA: if (cond) { x1 = 1; } else { x2 = 2; } x3 = φ(x1, x2); y1 = …  ( 7 min )

In the fast-paced world of web and mobile application development, delivering a seamless user experience is just as important as ensuring functional correctness. While traditional functional testing focuses on verifying if buttons work, forms submit correctly, and pages load as expected, it often overlooks a crucial aspect — how things look on the screen. This is where visual testing steps in. Visual testing goes beyond checking functionality; it ensures that the application’s user interface (UI) appears as intended. It helps detect visual bugs like misaligned elements, overlapping text, incorrect fonts, broken layouts, or color inconsistencies — issues that functional tests usually miss. Imagine a scenario where a “Submit” button works perfectly, but due to a CSS update, it’s now hidden b…  ( 10 min )

The previous article was dedicated to the Angular tool ng-virtual-list. Since then, the tool has acquired rich functionality, a number of significant improvements have been made to the virtualization and tracking algorithms, stability and performance have been increased. A port to React has also been implemented. It’s worth noting that ng-virtual-list is not just a virtualized list, it can optionally work as a virtualized select and multi-select; it can work with grouped lists, and in the future, collapsableGroups and multi-threading will be added. Now it’s time to test the full power of list virtualization in practice. Let’s define the design conditions of the viewport: Message list.

As blockchain moved from curiosity to mainstream, its environmental footprint sparked crucial conversations. This piece distills what “green blockchain” means, why it matters, and how the industry is steering toward energy efficiency without sacrificing security or decentralization. Many blockchain networks rely on a mechanism called Proof of Work (PoW). In PoW systems, independent participants (miners) compete to solve math puzzles, and the winner gets to add the next block of transactions to the chain. This race requires powerful hardware and, naturally, a lot of electricity. Bitcoin is the most famous example, where ongoing mining activity translates into substantial energy use and emissions when powered by fossil fuels. That surge in energy demand has raised questions: can blockchain s…  ( 8 min )

Introduction When I started working at Lingo.dev, I noticed that some Node.js packages were no longer needed since they could be replaced with native features. Similarly, modern browsers ship with dozens of lesser-known APIs. These native features handle everything from haptic feedback to barcode scanning, sometimes eliminating the need for external libraries. Here are 21 browser APIs with practical code examples for each. Web Share API The Web Share API lets you tap into the native sharing capabilities of the operating system. Instead of building custom share buttons for every platform, you can invoke the system's share dialog with a single API call. navigator.share({ title: 'Check out this article', text: 'Found this interesting article about browser APIs', url: 'https://exampl…  ( 9 min )

How to Search Electronic Components and Where to Find Them 1. Start with the Part Number The fastest way to search for an electronic component is by using its Manufacturer Part Number (MPN). For example, instead of searching for “ARM processor,” type “RK3588” or “STM32F103C8T6.” This eliminates ambiguity and helps you locate the exact product. If you don’t have the exact part number, try searching by: Manufacturer name + product family (e.g., "Texas Instruments LM317") Functional description (e.g., "3.3V voltage regulator, 1A") Several online platforms aggregate information from global distributors, making it easy to compare availability, pricing, and datasheets: Findchips – Searches multiple distributors, shows pricing, inventory, and alternatives.
